Thanks Mandeep, I'm not convinced a date effective prompt would help. This report is in the assignment events subject area and I needed the old and new position name for changes, but I've managed to find enough fields that are set up in the right way to get the data I need. The issue needs flagging with those responsible…

Just had the idea to try the Business Title and that is pulling today's data rather than the data from that assignment version. I should probably admit defeat and build a BIP report.
