We've got a QVW doc with a table that links USER to a field (REGION) in the doc. We can Loop and reduce on the REGION field via publisher and create the 5 documents for each region, but the proble we are having is how we distribute by looping through the USER field to apply doc security in access point. Publisher fails to identify a recipient and therefore the distribution isn't carried out.
The USER_REGION table in the doc looks as follows:
My first guess is that this is a problem either with the syntax or with case (as in upper vs. lower). Try changing this to user1@domain format and checking identity based on UserPrincipalName and see if that works.
