We have requirement where we need to update bseg-vbund( Trading partner) based on another line item vendor information.
We tried to implement a substitution for the same at call point 3.
as we need data of both GL and vendor line item data for deriving the logi.
But its not getting triggered.
We also looked for BADI/BTE for this updation purpose.
But none of these are getting triggered at 'save as completed' status.
Its getting triggered at Post option.
Please help if any body had ever worked on similiar requirements.
