CDS CURRENCY CONVERSION (ABAP on HANA)

Hi All,

I'v tested CDS with currency conversion versus the classical approach with the function module for currency converion on application layer (CONVERT_AMOUNT_TO_CURRENCY). The classical approach seemed to be much faster, so I started testing.

Please find attached the objects used for testin:

• y_cds_test_currconv.txt -> Simple ABAP report with both options
• Y_CDS_TEST_CURRCONV.txt -> The CDS view

I test on a system with AS ABAP 7.4 SP8 + HANA SP 8 and also AS ABAP 7.4 SP8 + HANA SP 9.

There's actually an OSS, but the it's refering to Oracle DB and not HANA DB (2067294).

Native SQL statment (tracing done with ST05)

SETSCHEMA"SAPMDE";

SELECT

   "CARRID",

   "CONNID",

   "FLDATE",

   "SOURCE_PRICE",

   "SOURCE_CURRENCY",

   "TARGET_AMOUNT",

   "TARGET_CURRENCY"

  FROM

    "YTESTCUR" ( "TO_CURRENCY" => 'EUR' ,

                              "EXC_DATE" => '20150427' ) "YTESTCUR"

  WHERE

    "MANDT" = '100'

Result

Change the CDS and replace the CURRENCY_CONVERSOIN by table field PRICE. (to check if the slow performance is cause by the currency conversion function)

Result run native SQL statement:

I have also run the SAP HANA Plan Visualizer, refer the next screenshots.

It seems to me that the currency conversion has some performance issue. Has anybody experienced the same and maybe found a solution?

One final remark: for testing you need to have data in FLIGHT model. (Go to SE38 and run SAPBC_DATA_GENERATOR to generate data)

Thanks in advance.

Best Regards,
