I got error at the time of PGI.
error is -
Document is incomplete: You cannot save the delivery
Message no. VU013
When the system checked whether saving delivery was permitted, it determined that the requirements stored in Define Incompletion Procedures for this document do not allow this subsequent function.
The system does not permit this subsequent function.
If this message appears during online processing, you can edit the document by choosing Edit -> Log of incomplete items.
