In the Inbound IDOC INVOIC, dynamically cost center determination needs to be determined based on some sales order data. For this I have found out an enhancement u2018FEDI0001u2019 under this, for cost center assignment user exit 002 u2018EXIT_SAPLIEDI_002u2019 (function Module exit) is suitable.
The problem that I am facing is, in this user exit sales order number and Line item number is not available based on which I would determine my cost center and assign it here. I have checked data in u201CEDI_FIELDSu201D table as well as all import parameters.
No field contains Sales order number and Item Number.
