Dear Expert,

Kindly please let me know if we can use the HANA SQL Function (Ex: ADD_DAYS, SECONDS_BETWEEN) in the select list of CDS Views?

If I create a CDS like below I get error that timestamp is not supported.

For Example:

@AbapCatalog.sqlViewName: 'ZMR_H_CA'

@EndUserText.label: 'CAG A'

define view viewname

with parameters start_ts:abap.dec( 15, 0 ) , end_ts:abap.dec( 15, 0 )

as select from table {

key resource_key,

TO_TIMESTAMP(begtstmp) as start_tmp,

TO_TIMESTAMP(begtstmp) as end_tmp

}

where

(begtstmp > $parameters.start_ts or endtstmp > $parameters.start_ts )

and

(begtstmp < $parameters.end_ts or endtstmp < $parameters.end_ts )

Thanks,

Giri

I had a requirement given by the business which was a bit difficult. The data was to be pulled from FI and MM module and combined in one report.

The report had to have 5 sections

1. For section 1 the data needs to be pulled from FI
2. Subtotal
3. For section 2 the data needs to be pulled from MM
4. For section 3 the data needs to be pulled from FI
5. Sub total
6. Grand total

I decided to explore all this by using the AMDP method. Given below is a screen shot of my procedure for the first 2 points.

I added one column called color in the structure which i will be using in the ABAP coding. I am also using the select from dummy to add a heading row.

Finally i do a union all and assign it in the out parameter of the procedure.

This is for retrieving the data

This is for the subtotal

In the ABAP Code

For coloring the line just add the line highlighted in the layout

The final out put

I Hope this helps the fans of code push down.

I am ABAP consultant having 9 years of exp. I want to do certification for ABAP for Hana.I found one certification with name SAP Certified Development Specialist - ABAP for SAP HANA (Edition 2014). In that i found below line written "This certification is issued to candidates who successfully pass the certification exam for the "SAP Certified Development Associate - ABAP with SAP NetWeaver" (C_TAW12_70, C_TAW12_71, C_TAW12_731, P_ABAP_70)."

Now my question is that I have not done any prior certification on ABAP. So Can i directly go for the ABAP for Hana certification or i have to first clear Abap with netWeaver first.

This is the 2nd blog from the DEV201@TechEd 2014 blog series which is compiling the demo-rich session DEV201 (Overview of ABAP 7.4 Development for SAP HANA) that was held at SAP TechEd && d-code 2014 in Las Vegas and Berlin. I'm also using this opportunity to refer you to some interesting blogs and documents available on the topic.

Full blog post series:

1. DEV201@TechEd 2014 Part 1: Introduction into ABAP 7.4 Development for SAP HANA
2. DEV201@TechEd 2014 Part 2: Detect custom ABAP code to be adapted (current blog)
3. DEV201@TechEd 2014 Part 3: Optimize your custom ABAP code & Explore the new opportunities (coming soon)

Let’s go ahead...

Detect ABAP custom code to be adapted

"Will my custom ABAP code still work on SAP HANA?"  is one of the major customer questions in the context of the migration of their existing ABAP-based software (e.g. SAP Business Suite or SAP Business Warehouse) to SAP HANA. The question mainly relates to two areas in which code corrections and adaptations may be required before the migration in order to avoid regressions:

• Functional correctness
• (SQL) Performance.

Before going ahead, I would like to draw your attention to the fact that a migration to SAP HANA is JUST a database migration. The different problematics are common to all databases, but their solutions may be database-specific. Therefore, there is nothing really new here! .

What should be detected?

Regarding the functional correctness: After a SAP HANA migration, everything works as before, except: Native SQL (EXEC or ADBC) with vendor-specific statements Database hints Non-robust code relying on undocumented behaviors such as implicit DB sorting order or access to technical pools/clusters of a pool/cluster table Code relying on the existence of secondary DB indices The detection of such code constructs is essential and their appropriate correction/adjustment are two mandatory

Regarding the performance: After a SAP HANA migration, a well-written ABAP code runs immediately faster, especially code with a long database processing time. And so remains a poorly-written code as such.   “Well-written” and "poorly-written" are meant here according to the classical performance rules for efficient SQL programming. Thus it is important to detect potential candidates for optimization by searching for critical SQL constructs - especially those ones with a low DB performance profile. Adapting them before the migration is not mandatory, but may be required in some cases.

The performance plays an important role during the whole software lifecycle - as regressions should be constantly avoided, thus the detection of tunable code is a task that is relevant before and after the migration in order to fully exploit the power of SAP HANA (refer to the classical and the adjusted SQL Performance rules).

But don't forget that you - as customer - are the one deciding how performant your application should be and so defining the scope of detection and optimization activities to be performed.

Which support do I get from SAP?

To assist you in your different detection activities, SAP NetWeaver AS ABAP 7.4 provides advanced quality assurance tooling. Three major tools can be named:

• ABAP Test Cockpit (transaction SATC)
• SQL Monitor (transaction SQLM)
• SQL Performance Tuning Worklist (transaction SWLT)

In the context of performance analysis, these tools provide an incredible support in identifying the most promising candidates for performance optimization (focus on hotspots). The tools can be used in a all contexts (HANA and non-HANA) and are also available on lower releases as part of the standard delivery as of AS ABAP 7.02 (SP12/SP14) or as ST-PI add-on.

ABAP Test Cockpit

The ABAP Test Cockpit (ATC) is the standard tool for running static code checks on ABAP development objects. The different findings (functional, performance, security, bugs, …) are reported in a prioritized list. The ATC framework enhances the well-known Code Inspector with new quality assurance processes such as quality gates, exemption approval process and periodic regression tests in a quality system. ATC is fully integrated in the standard development environments (with eclipse-based UI in ADT) and transport tools. Read more (general info)...

ATC is the basis for a smooth SAP HANA migration of custom ABAP code. It assists you in detecting potential functional and performance issues during the transition. As already mentioned. For this purpose, new checks and global check variants (FUNCTIONAL_DB and PERFORMANCE_DB) are provided. Read more (HANA specific)...

Remote static ABAP code checks can be performed on lower SAP NetWeaver releases where neither the check infrastructure or the new code checks are not available (refer to SAP Note 2011106).

SQL Monitor

SQL Monitor is the recommended standard performance analysis tool when it comes to the runtime monitoring of productive systems without impacting the running business processes. It allows the collection of an extensive set of runtime information (e.g. entry points, elapsed time, records read, …) for each and  every executed SQL statement and thus provides a transparent SQL profile of productive systems. The collected monitoring data are linked to their related ABAP processes (transaction, report name, …) and different aggregation and drill-down options to the related DB operations are provided. The integration of the SQL Trace (ST05) allows a more detailed investigation of given ABAP processes.

SQL Monitor supports you in identifying promising candidates for performance optimization with a high ratio performance improvement and optimization efforts. the tool is part of the standard delivery as of AS ABAP 7.02 SP14 and also available as ST-PI add-on (ST-PI 2008_1_700 SP8) for lower releases (ABAP 7.0 and beyond). Read more ...

SQL Performance Tuning Worklist

SQL Performance Tuning Worklist offers the possibility to combine the results from the static code checks and the runtime analysis, hence providing a more comprehensive view of the different results. The tool is quite helpful for beginners and advanced users while weighting the reported static check results. The typical approach is to start the identification of performance hotspots with the combined list and then to switch to the more powerful SQL Monitor to deepen the analysis of the root cause – as it provides more insights. The experience shows that experts will find their way directly into the SQL Monitor. Watch this video...

Guides and Best Practices

In addition to the advanced analysis tooling and the standard documentation in SAP Help portal, guides and best practices written by our experts are provided:

• Best Practice Guide - Considerations for Custom ABAP Code During a Migration to SAP HANA
• Optimizing Custom ABAP Code for SAP HANA – The New ABAP SQL Monitor
• Performance Guidelines for ABAP Development on the SAP HANA Database

In the next and last post of this blog series, I'll give a compact overview of the different programming capabilities delivered with AS ABAP 7.4 which can be used for writing ABAP code optimized for SAP HANA.

Hi All,

We are working on a HANA system which has several schema replicated from SAP R/3/Non SAP systems. We have BW 7.4 SP9 deployed on the same system and accessing the HANA views using latest BW virtual objects such as Open ODS , Composite providers etc.

We are also using the BW system for few ABAP based data processing developments. We are currently accessing HANA views in ABAP programs by creating dictionary views based on external HANA views.

We would like to however use recent possibilities of CDS and AMDP for better life cycle management of ABAP based solutions. The open SAP course on this subject was of very good help. Thanks a lot "open SAP team" for that. I would however have few open questions,

1. As I understand AMDP gives us full flexibility of writing sql procedures within ABAP development environment, but can we access tables from different schema into AMDP code. If yes, then sample code would help.
2. If the answer of first question is yes, then how do we manage transports between development and production systems where the schema names would be different. Currently in open HANA developments, such transport is manged using Schema mapping.
3. Can I also use different schema tables in CDS views.
4. We are updating few tables in ABAP dictionary after applying processing logic in ABAP program as detailed in step 1. With the new approach using AMDP, can we directly update database schema tables which will give us an optimization advantage.

New ABAP HANA program interfaces are quite promising and we would like to use them to optimize many data intensive applications.

Thanks & Regards,

Anil

Hi all,

I feel like I should be able to answer this question myself, but just can't seem to.

We run a BW system on HANA and last night had an overflow error during out batch loads:

• "Overflow converting '4812060' "

The data in question was successfully loaded to our PSA as a CHAR 20:

• "4812060"

My challenge is that the target field is an FLTP data type which I believe permits 16 characters - which I would have thought was sufficient for a number of this size?

• I'm struggling to reconcile the ABAP data type to the HANA data type for that field.
• The BW key figure in question uses the RSKYFFLO domain with an internal 'ABAP type' of "F" and an 'Internal length' of "8".

Can any one help explain why this failed?

(apologies in advance if this is as mundane as I expected, just can't figure it out)

Andrew

Hi Experts,

We have a client upgrading to HANA so there are many reports that we would like to code pushdown.

There are certain challenges that we are facing while creating procedures like:

The existing report has many loops and read statements inside so we are planning to bring that logic down inside Procedures.

As of now all the Select Queries have been incorporated via CE Functions inside the Procedures but the main challenge now is how to code for loop and read statements inside procedures.

I would like to put a loop on the output parameters below:

Also,Is it a good practice to remove all the loops and read statements and writing them in Procuderes or just leave them as it is and just put the Select Queries inside Procedures.

Below is the code that we want to have inside our procedures:

     LOOP AT i_vbfa INTO w_vbfa WHERE vbelv = w_vbak-vbeln.

       READ TABLE i_vbrk INTO w_vbrk WITH KEY vbeln = w_vbfa-vbeln

                                              fkart = 'ZRBC'.

       IF sy-subrc = 0.

         v_fkdat =  w_vbrk-fkdat.

         IF w_vbrk-zzbelnr IS INITIAL.

           lv_rbc = 'X'.

         ENDIF.

       ENDIF.

       READ TABLE i_vbrk INTO w_vbrk WITH KEY vbeln = w_vbfa-vbeln

                                                fkart = 'ZRBM'.

       IF sy-subrc = 0.

         lv_rbm = 'X'.

       ENDIF.

       CLEAR: w_vbfa,

              w_vbrk.

     ENDLOOP.

I guess we would have to use For and Cursor Statements but never used them.

Thanks,
Gaurav

Hi All,

We need to create an AMDP for accessing tables from different schemas with SLT replicas of different ERP instances.

Does someone know if it's possible to parameterize schema name on AMDP so it's possible to use the same stored procedure for accessing the same tables on differen schemas on the same HANA DB instance?

Best regards

Fernando Alvarez

i have a requirement that i have to send one mail to the customers billing details to the related customers. i am trying to convert the spool request into pdf format but i won't be able to send the mail. whenever i am checking in SOST tcode the mail was in queue and when i select the mail and i click display then one popup came... i don't understand why it is coming.

Hello Folks,

Can anybody explain me how to use select options inside AMDP method.

Regards,

Amol

Hi,

I want to pass select options and internal table to a procedure at the same time. How can we do that?

I know we can pass select options to Calculation View but in that case also AFAIK we cannot pass internal tables to the Calc View.

Here is the code for example:

SELECT * INTO CORRESPONDING FIELDS OF TABLE pct_vbreveav

                   FROM vbreve

                   FOR ALL ENTRIES IN lvt_control

                   WHERE vbeln        =  lvt_control-vbeln AND

                                   posnr        =  lvt_control-posnr AND

                                   bdjpoper  IN lvt_bdjpoper      AND

                                   vbeln_n    IN s_vbeln_n.

I want to pass Select Option 'S_VBELN_N' and internal table 'LVT_CONTROL' at the same time.

Thanks,

Gaurav

We're reaching the of the DEV201@TechEd 2014 blog series which is compiling the demo-rich session DEV201 (Overview of ABAP 7.4 Development for SAP HANA) that was held at SAP TechEd && d-code 2014 in Las Vegas and Berlin. I'm also using this opportunity to refer you to some interesting blogs and documents available on the topic.

The blog series comprises three posts:

• DEV201@TechEd 2014 Part 1: Introduction to ABAP Development for SAP HANA
• DEV201@TechEd 2014 Part 2: Detect custom ABAP code to be adapted
• DEV201@TechEd 2014 Part 3: Optimize your custom ABAP code (current blog)

Please bear with me here, for the lengthy blog - It's the last of the series...

Optimize your custom ABAP code

SAP NetWeaver 7.4 (and releases beyond) offers various programming capabilities that should be used to easily develop ABAP applications best leveraging the power of HANA, i.e., high performance and advanced native functions such as financials, text mining and predictive analysis. The majority of these new features works on all SAP supported databases (anyDB), but are optimized for in-memory databases such as SAP HANA. So just a few is solely supported on HANA.

Following capabilities were introduced and demoed during the session:

• SAP List Viewer with Integrated Data Access (ALV with IDA)
• Search Helps with type-ahead function and full-text search
• Enhanced Open SQL
• Advanced view building with ABAP Core Data Services (CDS)
• Easy access to native HANA capability with ABAP Managed Database Procedures (AMDP)
• Real-time eventing with ABAP Channels

Where in the world do I start? may be the question coming up to your mind when you think of writing ABAP code that is optimized for HANA.

Well, we strongly recommend to start with "low hanging fruits" (so-called Quick-Wins) and then to evolve naturally -as the requirement get's more complexe- to the more advanced capabilities. This means check which features fits to your requirements and choose the one where you have the most skills.

Start with low hanging fruits

It's all about first making use of well-known capabilities that have been enhanced or optimized for HANA. For example, the screenshot above shows a FPM application which makes use of the HANA-optimized ALV re-use component and the fault-tolerant search (aka Fuzzy Search) in the Search GUIBB.

The application runs in SAP NetWeaver Business Client with an analytical side panel (on the right side) using HANA capabilities which provides more insights to the transactional application.

SAP List Viewer with Integrated Data Access (ALV with IDA)

ALV with IDA (aka ALV on HANA) is a re-use component which offers the well-known functionality of the classical ALV optimized for in-memory DBs such as HANA. It is a good example for showcasing the implementation and the benefits of the Code-to-Data paradigm in ABAP.

Search Helps with type-ahead and fault-tolerant search

You now have the possibility to enhance the functionality of a search help object (F4 Help) with a type-ahead and fault-tolerant full-text search. The type-ahead (aka search-as-you-type) function allows a faster user interaction by showing possible search results from the standard F4 help already while typing in a drop-

down box beneath the search field. This option works on anyDB.   In addition, the Full Text Fuzzy Search option can be activated. It offers a fault-tolerant cross-column search. This option is DB-specific and currently only supported on HANA.   As a developer, you do not have to modified their UIs in order to enable the enhanced functionality. What you have to do, is simply to select these options in the relevant search help object (SE11).

The enhanced search help functionality is currently only supported in classical dynpros. Watch here ...

Enhanced Open SQL

Open SQL is an abstraction layer defining a common syntax and semantics for all SAP certified databases. It has been enhanced and now offers a broader coverage of standard SQL features.

This enhancement allows a better support of the Code-to-Data paradigm by using extended joins support, sub-queries, SQL functions, expressions, aggregations and many more.

A new Open SQL syntax (with comma separated SELECT list and escaping of host variables with @) was necessary to achieve this. The old syntax is still supported, but the new one is mandatory for a given statement if it makes use of new features. Read more...   PS: In case you are already on ABAP 7.4 and are preparing your code for a HANA migration, then always first try to replace problematic native SQL statements (EXEC and ADBC) with Open SQL.

Advanced view building with ABAP Core Data Services (CDS)

CDS is SAP's next generation of data definition and access for database-centric applications. It uses and extends SQL to capture the business intent. Its integration into the ABAP server provides a new DB abstraction layer simplifying and harmonizing the definition and consumption of semantically rich data models regardless of the application domains (e.g. transactions and analytics) across different SAP platforms.

The Code-to-Data paradigm is supported through e.g. various built-in functions, unions, associations and path expressions. ABAP CDS is integrated in the ABAP dictionary. The CDS views are ... defined in a text-based editor (only in ADT) fully and solely managed by AS ABAP supported on anyDB (native integration in HANA) consumed in Open SQL like SE11 views extensible on model level using modification-free view enhancements and on meta-model level using domain-specific annotations Read more...

ABAP Managed Database Procedures (AMDP)

Database procedures are subroutines for processing application logic directly in the database. HANA offers procedures in SQLScript (an extension to SQL) which allow followings:

expression of complex logics (incl. if/else) definition of local variables parametrization of requests multiple result sets   With AMDP, a class-based framework for managing and calling HANA procedures in AS ABAP, a deeper integration of both worlds is provided. It allows you to fully and easily expose the power of HANA (high performance and advanced native functions) in ABAP applications.   AMDP are provided by mean of marked methods of global classes implementing specific tag interfaces. These so-called AMDP classes and methods can only be edited with ADT and are called in programs like regular ABAP methods.

ABAP developers remain in their familiar development environment and can make use of well-known and robust ABAP concepts and techniques such as the Enhancement Framework and the standard transport mechanism (same by CDS). Read more...

Real-time eventing with ABAP Channels

This functionality is not HANA-specific and works on anyDB. I smuggled it into the session simply to let you know about this cool stuff. And since we're talking about real-time processing, real-time eventing just fits.

Short: ABAP Channels (ABAP Push Channels + ABAP Messaging Channels) enable the support of event-driven interactive and collaborative scenarios by providing an implementation of the WebSocket protocol in ABAP. So, stop polling and start real-time eventing! Read more...

Explore new opportunities

Scenarios and applications that weren't possible in the past due to technical restrictions are now reality thanks to the breakthrough technology that is HANA. The possibility is now given to you to rethink both, the way you do business and the way your build applications!

With all these new programming capabilities (especially with AMDP) provided as of AS ABAP 7.4, you can fully and easily integrate the power of HANA in your existing business and e.g. support more agile processes with new innovative applications which were not possible before for performance reasons.

Check it out. SAP HANA - Simplify - Accelerate. Innovate.

That was it. You'll find a comprehensive explanation of the different ABAP language features in the ABAP Keyword Documentation.

Stay tuned and get your hands dirty.

Hi Gurus,

How to call cross schema dictionary tables, AMDP and views in AMDP method.

E.g.

METHOD sflight BY DATABASE PROCEDURE

                          FOR HDB

                          LANGUAGE SQLSCRIPT

                          OPTIONS READ-ONLY

                          USING sflight d10.lfa1. <-- cross schema table.

Hi,

I installed SAP HANA developer edition 1.0 Rev 80 on the AWS and all looks good. But when I try to find the ECC tables like MARA or KNA1 to do some exercises as mentioned online and in SAP study material, i dont find the tables in any catalog. The materials and videos talk about catalogs like 'training' which are not there in the edition I installed. I only see SFLIGHt related tables.

I tried searching the forum and online but could not find info. Could you please help me understand what I need to do to get these tables?

Thanks,
