Need to update XREF2 and XREF3 fields while creating Invoice using BAPI_INCOMINGINVOICE_CREATE
We are trying to create a Invoice using the FM BAPI_INCOMINGINVOICE_CREATE.
Now we need to update the fields XREF2 and XREF3 of BSEG which is not present in the BAPI parameters.
The client will pass the values in extension table BAPIPAREX. Now we are trying to update the XREF2 and XREF3 using a FI Substitution, but I am not able to read the Extension Table value in the Substitution.
