Bruce made changes regarding processing tables that have a DeletedTimeStamp field.
NT 10.16
Add: Web apps now filter out all records with DeletedTimeStamp set from every VIEW by default. Can display deleted records by setting p_web.RemoveDeletedRecords = false.
I'm paraphrasing quite a bit and I'm sure Bruce will clarify.
A procedure that uses a VIEW, browses being the most common, will now automatically filter out "deleted" records.
If you haven't already, I would add the ServerTimeStamp, TimeStamp, and DeletedTimeStamp fields, along with keys, to the table of the offending procedure.
See if that helps,
Don
