get purch_group id from function 'BBP_PD_PO_GETDETAIL'
i want to retrieve the purchasing group id .
For that, i am calling the function ' BBP_PD_PO_GETDETAIL' and using table result E_ORGDATA and retrieving the purch_gp from field PROC_GROUP_ID.
But, i noticed that sometimes table E_ORGDATA is empty.
Do anyone has an idea about the root cause of this issue?
