A lot of libraries would like to add the basketname or the order number to the email subject of ACQORDER. The test plan on bug 21898 included the case, but it doesn't appear to work.
Marking as a bug fix because of the 'promise' of bug 21898 :)
This turns out to be a duplicate of bug 31587, the patches there also make the basket information available on the subject line. *** This bug has been marked as a duplicate of bug 31587 ***
