Are you able to share copies of the report and model privately? If so I could take a look at it as a second opinion.
There have been a few anomalies in certain aspects of MCR processing but they appeared rarely and I don't recall this one specifically. But then I don't recall attempting the sort of extract you have described either. May have done it but I don't recall.
Let me know if you are allowed to share and I will send you a PM with an email address to send to.
Alternatively you could try the Tech Support guys at Datawatch who are likely to have some insights about this I would think, based on knowing the differences in this area of functionality, if any, between V9 and V10 better than I do.
The report is sensitive of course but I can probably truncate it to a useable section that would be acceptable to my powers that be.
I would love a second opinion. It seems to be relative to the fact that it is an append. If I switch it to footer if pulls through. But unfortunately, it is not a footer so it pulls through wrong.
I also submitted this to tech support this evening as I am growing more and more convinced it's an upgrade issue. Considering everything I put IT and the 21 other users through because of the .net3, I would hate to roll back.
