BPC 10.0 Script Logic: Combination of *FOR *WHEN *LOOKUP

Hi experts,

I'm working on a requirement to copy values from one model to another and aggregate to values.

Basically my script looks like that:

...

*LOOPUP OTHER_MODEL

*DIM VERSION = VERSION

*DIM TIME = TIME

*FOR %LOOP_CST% = %COSTCENTER_SET%

*DIM CST_%LOOP_CST%: COSTCENTER = %LOOP_CST%

*NEXT

*ENDLOOKUP

*FOR %SEL_CST% = %COSTCENTER_SET%

     *WHEN COSTCENTER

     *IS = %SEL_KST%

          *WHEN COST_TYPE

          *IS = "CST_NA"

               *REC(EXPRESSION = LOOKUP(%SEL_CST%), COSTCENTER = [COSTCENTER].AGGR_LEVEL, CURRENCY = "CURR_NA")

          *ELSE

                *REC(EXPRESSION = LOOKUP(%SEL_CST%), COSTCENTER = [COSTCENTER].AGGR_LEVEL, CURRENCY = "EUR")

          *ENDWHEN

     *ENDWHEN

*NEXT

*COMMIT

Unfortunately, this is not working.

If I include the for-loop inside the when-loop it is working. However, the values are multiplied based on the number of records.

Is there another possibility to solve this issue?

Thanks in advance,

Benjamin
