Error in output determination via collective billing VF06
We are facing error in output determination when collective billing is done. Multiple Orders numbers are entered in VF06 and processed to generate billing documents. VF06, which is used for batch billing, creates a batch job which internally calls VF04 to do this. For some of the invoices generated from the documents, we do not have anything in the Output, i.e. when we open the invoices in VF03 and go to Goto->Header ->Output, nothing appears.
Say out of the 5 documents, 2 should have output determined and 3 do not. Then we see that it appears for either of the 2 or does not appear at all.
This does not happens when the documents are processed one by one in VF04. We have to do collective billing and generate one invoice for each document.
