Hi Gurus,
I want to write ABAP programs from hana studio, i have added ABAP plugins to hana studio.
But after adding these plugins I am trying to add systems from SAP logon pad.
But I am getting below error.
User is not authorized to access system ECS using ABAP in Eclipse (The system does not support Eclipse based ABAP Development Tools).
Please let me know what could be remedy for this.
Regards,
Rahul
Hi All, following on from looking at ABAP Managed Database Procedures I started looking at CDS views on our CRM on HANA system and wanted to see what was happening at the HANA layer and how the views performed.
Note: our CRM is on ABAP 7.4 and HANA Rev 73.

So first off I created the CDS view. My view is based on Business Partner details. In my project I created a new DDL source and added the following:
@AbapCatalog.sqlViewName: 'ZPM_V_PARTNERS' define view zpm_partners as select bt.partner, bt.name_org1, bt.name_last, bt.name_first, bt.type, partcat.ddtext, bt_fs.addrnumber, adrc.name1, adrc.city1, adrc.city2, adrc.home_city, adrc.street, adrc.post_code1, adrc.house_num1, adrc.house_num2, adrc.building, adrc.floor, adrc.roomnumber, adrc.country, adrc.region from but000 as bt left outer join dd07t as partcat on bt.type = partcat.domvalue_l and partcat.domname = 'BU_TYPE' and partcat.as4local ='A' and partcat.ddlanguage = 'E' left outer join but021_fs as bt_fs on bt.partner = bt_fs.partner left outer join adrc as adrc on bt_fs.client = adrc.client and bt_fs.addrnumber = adrc.addrnumber and adrc.langu = 'E'
I saved and activated the view successfully. I then went to the HANA layer and took a look at what was created there. In our CRM schema I found the new view ZPM_V_PARTNERS:

Clik here to view.
On opening the definition I could see the following create view statement:
CREATE VIEW "SAPSR3"."ZPM_V_PARTNERS" ( "MANDT", "PARTNER", "NAME_ORG1", "NAME_LAST", "NAME_FIRST", "TYPE", "DDTEXT", "ADDRNUMBER", "NAME1", "CITY1", "CITY2", "HOME_CITY", "STREET", "POST_CODE1", "HOUSE_NUM1", "HOUSE_NUM2", "BUILDING", "FLOOR", "ROOMNUMBER", "COUNTRY", "REGION" ) AS SELECT "BT"."CLIENT" AS "MANDT", "BT"."PARTNER", "BT"."NAME_ORG1", "BT"."NAME_LAST", "BT"."NAME_FIRST", "BT"."TYPE", "PARTCAT"."DDTEXT", "BT_FS"."ADDRNUMBER", "ADRC"."NAME1", "ADRC"."CITY1", "ADRC"."CITY2", "ADRC"."HOME_CITY", "ADRC"."STREET", "ADRC"."POST_CODE1", "ADRC"."HOUSE_NUM1", "ADRC"."HOUSE_NUM2", "ADRC"."BUILDING", "ADRC"."FLOOR", "ADRC"."ROOMNUMBER", "ADRC"."COUNTRY", "ADRC"."REGION" FROM ( ( "BUT000" "BT" LEFT OUTER JOIN "DD07T" "PARTCAT" ON ( "BT"."TYPE" = "PARTCAT"."DOMVALUE_L" AND "PARTCAT"."DOMNAME" = 'BU_TYPE' AND "PARTCAT"."AS4LOCAL" = 'A' AND "PARTCAT"."DDLANGUAGE" = 'E' ) ) LEFT OUTER JOIN "BUT021_FS" "BT_FS" ON ( "BT"."CLIENT" = "BT_FS"."CLIENT" AND "BT"."PARTNER" = "BT_FS"."PARTNER" ) ) LEFT OUTER JOIN "ADRC" "ADRC" ON ( "BT_FS"."CLIENT" = "ADRC"."CLIENT" AND "BT_FS"."ADDRNUMBER" = "ADRC"."ADDRNUMBER" AND "ADRC"."LANGU" = 'E' AND "BT"."CLIENT" = "ADRC"."CLIENT" ) WITH READ ONLY
Nothing too out of the ordinary here except I did notice one subtle thing - the inclusion of opening and closing brackets () around the datasource joins.
(( "BUT000" "BT"
LEFT OUTER JOIN "DD07T" "PARTCAT" ON ( "BT"."TYPE" = "PARTCAT"."DOMVALUE_L"
AND "PARTCAT"."DOMNAME" = 'BU_TYPE'
AND "PARTCAT"."AS4LOCAL" = 'A'
AND "PARTCAT"."DDLANGUAGE" = 'E' ) )
LEFT OUTER JOIN "BUT021_FS" "BT_FS" ON ( "BT"."CLIENT" = "BT_FS"."CLIENT"
AND "BT"."PARTNER" = "BT_FS"."PARTNER" ) )
LEFT OUTER JOIN "ADRC" "ADRC" ON ( "BT_FS"."CLIENT" = "ADRC"."CLIENT"
AND "BT_FS"."ADDRNUMBER" = "ADRC"."ADDRNUMBER"
AND "ADRC"."LANGU" = 'E'
AND "BT"."CLIENT" = "ADRC"."CLIENT" )
Would this have an affect on the execution and performance of the query? To investigate this I decided to compare the execution of the view with the execution of the raw SQL query.
In my HANA Studio SQL Editor I queried the view for one business partner a number of times to get the average execution time:
select * from "SAPSR3"."ZPM_V_PARTNERS" where partner = '1000184087'
And then executed the raw query without any of the opening or closing brackets querying the same partner:
select bt.partner, bt.name_org1, bt.name_last, bt.name_first, bt.type, partcat.ddtext, bt_fs.addrnumber, adrc.name1, adrc.city1, adrc.city2, adrc.home_city, adrc.street, adrc.post_code1, adrc.house_num1, adrc.house_num2, adrc.building, adrc.floor, adrc.roomnumber, adrc.country, adrc.region from sapsr3.but000 as bt left outer join sapsr3.dd07t as partcat on bt.type = partcat.domvalue_l and partcat.domname = 'BU_TYPE' and partcat.as4local ='A' and partcat.ddlanguage = 'E' left outer join sapsr3.but021_fs as bt_fs on bt.partner = bt_fs.partner left outer join sapsr3.adrc as adrc on bt_fs.client = adrc.client and bt_fs.addrnumber = adrc.addrnumber and adrc.langu = 'E' where bt.partner = '1000184087';
The SQL plan cache was interesting. The raw SQL query without the opening and closing brackets was 3 times faster than the query on the view.

It would seem that the brackets are causing the view to perform slower. Just to confirm I took the SQL from the generated view and executed that a number of times querying on the same partner again:
SELECT "BT"."CLIENT" AS "MANDT", "BT"."PARTNER", "BT"."NAME_ORG1", "BT"."NAME_LAST", "BT"."NAME_FIRST", "BT"."TYPE", "PARTCAT"."DDTEXT", "BT_FS"."ADDRNUMBER", "ADRC"."NAME1", "ADRC"."CITY1", "ADRC"."CITY2", "ADRC"."HOME_CITY", "ADRC"."STREET", "ADRC"."POST_CODE1", "ADRC"."HOUSE_NUM1", "ADRC"."HOUSE_NUM2", "ADRC"."BUILDING", "ADRC"."FLOOR", "ADRC"."ROOMNUMBER", "ADRC"."COUNTRY", "ADRC"."REGION" FROM ( ( sapsr3."BUT000" "BT" LEFT OUTER JOIN sapsr3."DD07T" "PARTCAT" ON ( "BT"."TYPE" = "PARTCAT"."DOMVALUE_L" AND "PARTCAT"."DOMNAME" = 'BU_TYPE' AND "PARTCAT"."AS4LOCAL" = 'A' AND "PARTCAT"."DDLANGUAGE" = 'E' ) ) LEFT OUTER JOIN sapsr3."BUT021_FS" "BT_FS" ON ( "BT"."CLIENT" = "BT_FS"."CLIENT" AND "BT"."PARTNER" = "BT_FS"."PARTNER" ) ) LEFT OUTER JOIN sapsr3."ADRC" "ADRC" ON ( "BT_FS"."CLIENT" = "ADRC"."CLIENT" AND "BT_FS"."ADDRNUMBER" = "ADRC"."ADDRNUMBER" AND "ADRC"."LANGU" = 'E' AND "BT"."CLIENT" = "ADRC"."CLIENT" ) where bt.partner = '1000184087';
As expected the SQL plan cache showed similar average run-time to the view.

Clik here to view.
To take it a bit further I took a look at the viz plans of the view and the raw SQL (without the brackets).
Straight away it was easy to see the differences in the plan. For reference purposes I have attached the viz plans to the blog.
Here is the overall view of the viz plan for the CDS View:

On drilling down:

On analysis, first off it joins BUT000 to BUT021_FS, assembles the results, then joins ADRC to DD07T, assembles the results and then joins up these 2 result sets all in a linear execution it seems.
And here then is the viz plan for the direct query

As you can see from the plans for the direct query the joins on BUT000 and DD07T and the joins on ADRC and BUT021_FS look to be done in a parallel execution and then the results are assembled.
Conclusion
So the inclusion of the opening and closing brackets surrounding the datasource joins are resulting in a different execution plan for the view compared to the execution plan of the directly executed query. From the evidence above this has a negative impact on the execution time of the view. Would be interesting to hear from some SAP folks if this is by design and if so are there best practice gudelines available in terms of performance optimization on CDS views....

Hello colleagues,
is it possible to generate/create DB procedure proxies dynamically within ABAP?
So we know the DB procedure name and want to create a DB procedure proxy dynamically in ABAP.

Hi,
I have one more important question.
How ADBC connection is benefits by using SAP HANA as secondary database in terms of performance wise for the access of data from HANA database as a secondary database.
I have 2 options and which is better for the good performance for accessing the data-
1 . In ABAP Reports in the SELECT statements by using CONNECTION (“HDB”) will this improve the
performance.
e.g : select * from BSEG into TABLE IT_TAB CONNECTION (“HDB”).
2. Will Create the Stored procedure in HANA studio and Call
from ABAP as below by using NATIVE SQL–
EXEC SQL
SET CONNECTION (‘HDB’).
ENDEXEC.
EXEC SQL.
EXECUTE PROCEDURE proc (IN p_in1
OUT p_out1 OUT p_out2 )
ENDEXEC.

Pravin

Hello,
does anyone know if there is a possibility to delete a graphical HANA view (attribute/analytical/calculation view) from ABAP source code, e.g., using an SQL statement or an ABAP method.
Kind regards,
Sven
Hi All,
When you set the 'Enforce SQL Execution' in the Graphical View..SQL Engine is used for calculations
I'm having some issues with Null Values
Something like this won't work if any of the values are NULL in SQL Engine
“INT_COL_1” + “INT_COL_2”
So we have to replace the above statement with sqladd("INT_COL_1", "INT_COL_2") right ?
Does anyone have a reference document where i can find this statements
Thanks in advance

Hello Gurus,
Recently my client is going on for Sap Hana Consolidation and SLO (System Landscape Optimization) project with existing Sap Solutions ( SRM, BW, Portal , PPM , ECC and PI) . Now I want to know the possible ways to perform this. As we are moving on one system on client for SAP Hana Platform. Can someone guide me the correct process regarding above migration.Mainly the project scope is :-
Please provide me the idea for above process to be performed.Can some one provide me better guidance for this .

Hi ABAP on HANA Gurus,
I think by this time, most of us are aware of the difference between Row Store and Column store in SAP HANA ( Column store actually uses an internal memory layout, which is highly optimized for column operations such as search and aggregation.)
Recommendation from SAP is to always use Column store for tables with Business Data (i.e. Master Data and Transaction data ) within SAP HANA and Row Store to be used very selectively for Application server system tables. I have these queries :
1. What kind of system tables are referred here ?
2. Can we use Row store for Configuration tables ? In this case, we can optimize the query by using SELECT SINGLE * for required condition.
3. For Side car scenarios, where in we may have SAP ERP on Classical d/b and required Tables/data are replicated to HANA by SLT, then I understand that SLT would automatically decide which tables will be Column Store and Row store.
4. Are the recommendations different for Suite on HANA ? I think a Hybrid Row and Column store is used here to provide optimizations in the OLTP system.
5. So, what is the approach to be followed when we are doing any Native HANA development and we need to create few Custom tables. Although by default, they need to be Column store, are there any special cases to be considered for Row store ?
Thanks,
Suma
