Are you talking about the FM36 monthly payment report?
If so, you will see the UKPRN against the rows for subaims, but not for the generic programme aim (ZProg), as the ILR doesn’t currently have a field for subcontractor UKPRN at programme level, only at main and subaims. FM36 doesn’t pay against the main aim, but against the programme.
I have to run a report out of Maytas with subcontractor info, and vlookup into the payment report to get the subcontractor info.
Look at column H Learning Aim Title. No main aims show (as no funding attached), just the programme aim or subaim. Nowhere on the ILR to put UKPRN against programme. That’s probably where you have your blanks.
