I also noticed this and reported it to the service desk and got the following reply…
Thank you for contacting the Service Desk
The data team are currently reviewing the reports to ensure they are as accurate as possible. I can confirm that the Software supplier ID field would not affect funding and is being looked into for the R05 reports.
That is an appalling response from the ESFA. They seem to have no appreciation of the problems they cause. Whilst they assure that the money is correct, not being able to check and confirm this is of zero interest to them.
