Hi Amit,
We have already tried an enhancment on exit -EXIT_SAPLWPUE_102
However, during IDOC posting, still we find the determination is being overrided.
One part of the structure that we find in the function ue_sales_document_process is in the code g_filialstamm that overrides the changed organization with the site default organization.
Not sure how to fix and will there be other areas that need to be fixed.
Thanks
Caroline
