Virtual characteristics or key figures load data with BIA/BWA?

Hello,

we have the following question: Do virtual characteristics or key figures use the BIA/BWA for loading data or do they load without acceleration direct from the database?

Thanks in advance!

Regards,

Hi Torben. Please have a look at OSS Note 1143411 - "BIA, virtual key figures and characteristics"

Also look at the Note 1088469 - Enhancement in exit "virtual characteristics/key figures" - see below. With MODE=2 it should work

The exit for virtual characteristics and key figures (Business Add-In RSR_OLAP_BAD or customer exit RSR00002) has been enhanced.

In the list of characteristics C_T_CHANM in method IF_EX_RSR_OLAP_BADI~DEFINE, you can also enter the mode RRKE_C_MODE-CHNG_W_SEL (MODE = 2) in the MODE field for a characteristic.

As with the mode RRKE_C_MODE-NO_SELECTION, you can change the characteristic values in the actual calculation of the exit (method IF_EX_RSR_OLAP_BADICOMPUTE). In the mode RRKE_C_MODE-NO_SELECTION, the selections for the characteristic cannot be transferred to the database/SAP NetWeaver BI Accelerator (BIA). In the mode RRKE_C_MODE-CHNG_W_SEL, the global filters of the query are transferred to the database/BIA. When this mode is used, ensure that the filter in the query definition is set so that the relevant records are still selected. The records that fulfill the conditions of the filter are transferred to the method IF_EX_RSR_OLAP_BADICOMPUTE. Afterwards, the changed data is checked against the filter again.

Hi Torben,

If your scenario is BW-BWA, just the physical characteristics and key figures are loaded to BWA server (in-memory). The great performance gain with BW Accelerator will be on selection data time in the database, and if you are using a customized abap code in user-exit variable of query (virtual) this part of execution time of query will not accelerated with BWA.

Best regards,
