I am attaching a document that is been created through CV01N to transaction VA02 at item level.when i am trying to put that document no. at item level on the Extras-Documents- system is giving me a message as "Document type doesnot allow you to assign to object VBAP".
similarly if i take this document no from F4 screen,it comes but when i check the same after saving the document gets disappeared.
while the same document is getting attached at material master easily.
I think some customization is missing for the same..plz let me what i need to do to resolve the same.
Thanks & Regards,
