It seems to me that the Data Reduction step is somehow messing with the access to this document.
IAfter you added those new groups to your Section Access table, is everyone having trouble opening this document? Or just the users that belong to these new groups?
BTW which version of QV are you running?
Thanks for taking a look at my problem, Peter.
I'm running 12.10.
I think you're spot on with something going wrong in Data Reduction. If I key that user to an "old", working group, I can open the properly filtered document on the Access Point, so I guess it's save to say (even though I'm working on a copy of the document in use by our users) that it has somehow got to do with the added groups.
