When
When we have more than one title received on the same order, we make the
titles that are not to have payment data with values of q in the XPM field
(paid elsewhere).  You also cannot have a fund code in the OPR when you
choose to use the q value.  It is also my experience that even though
titles are part of the same subscription or membership they often have
different vendor title numbers.  Also with the q value, the order record is
not expecting payment so I don't think you would get a message on the VITLS
error reports.
This is in response to Donna Alsbury's query about VITLS.
