Modify Sales Invoice that created from Job Planning Line

swj

Hello,

can someone please advise what is the correct way to modify Gen. Prod. Posting Group in Sales Invoice that created from Job Planning Line?

There is error message when tried to modify Gen. Prod. Posting Group in Sales Invoice that created from Job Planning Line.

"Job Contract Entry No." must be 0 in Sales Line .....

Since "Job Contract Entry No." will have value if Sales Invoice is created from Job Planning Line.
What is the correct step if we want to update Gen. Prod. Posting Group? Should we have to delete the line, and recreate again from Job Planning Line?

It would be quite trouble some... :-#

THANKS
