I am currently trying to resolve a user authorization problem to tcode FBV0.The message that the user gets on trying to post the invoice is "Document cannot be posted since document balance is not zero". On the look of it it does not seem to be an authorization message.But the irony is that another user with a different role is able to post the document. I had myself tried to post a similar document by giving myself the authorizations and was able to do so.Trace & SU53 do not give the correct values for missing authorizations. I have added the following objects with values as below, but it does not seem to work. Any pointers towards this issue will help resolve the problem.
