Delivery Item Category

Dear All,

I was trying to copy a Standard Del Item Category ( DLN ) i got an Error " Entry Does not exist in TVPT (Check Entry).

To solve this error i created a dummy item category ZDLN at VOV7.Then i tried to copy the Standard Del Item Category DLN to ZDLN. It worked fine and i was able to copy DLN as ZDLN.

I have checked TVPT - it is Sales Documents Item Categories table.

My doubt is if an entry (Ex: ZDLN) does not exist at VOV7 can't we create or copy the same entry at Del Item Category?What is the link between Sales Document Item Category and Del Item Category? Please throw some light on this.

Thanks and Regards,

Aditya
