In SRM 7.0 system we couldnt able to run the BDC in BBP_POC transaction(in SRM 3.0 it is BBPPO01). I tried using the FM
BBP_PD_PO_UPDATE to update the cost center. But is is not working.
I have used BBP_PD_PO_GETDETAIL
Afterwards BBP_PD_PO_UPDATE ,
BBP_PD_PO_SAVE and BBP_PROCDOC_RESET_BUFFER.
Please give your valuable inputs to solve this issue.
