A couple of things to note here:
- The user is trying to reverse billing from start of January and now it is end of February. Is he even allowed to do that per your corporate policy rules - especially if this is indeed inter-company related?
- Even if the user cancels the billing, then what would be the next step? What he is planning to do with the inventory? Was this quantity physically received or not, if not - was it already posted as inventory differences during monthly count?
- Exact error message:
system is throwing an error like "Cancelled document can't be cancelled"
Being an old SCN member and a consultant, you already know that for many people posting in the forum English is not the default logon language and some of them are not native English speakers. The exact message class and ID of the error are very important for troubleshooting and investigation.
In your case I suspect that the error is VF108. If this is correct, you could simply use it as a criteria in the forum search function. It produces just a few results, which take minutes to read, and in one of them there is a very detailed explanation why/when this happens and points to consulting sap notes how to resolve this specific issue.
I am not adding the link on purpose, because going through 4 threads does not require significant effort.
- Siva Prasad Vasireddy, from what I know, Complete in VF02 works only for proforma invoices in non-modified systems. Please correct me if I am wrong and if this was changed in releases after ECC6 EhP4:
