RTI - B2A Manager

Hello All,

The issue I'm facing is when submitting RTI files to HMRC an error message appears in B2A Manager even though the file has been successfully submitted. I know the files are getting successfully submitted because we get a confirmation email from HMRC but the B2A Manager is incorrectly displaying an error message. This used to work absolutely fine before but something has gone wrong.

Any ideas?

Thanks

Mike
