Hi,
maybe this fm can't be called alone, maybe some other fm's of function group WVKC have to be called before.
Have a look into include LWVK1F6K how to fill structure parameter PISPR:
perform pispr_aus_kalp using pi_vkkam px_iniam yes.
* end of insertion WRF_PPW_RPC
pispr-mgame = mgame_kalk.
call function 'SALES_PRICE_READ_INITIAL'
exporting
pi_i_spr = pispr
...
Regards,
Klaus
