Sales CIS submission problem
Question asked by D NEMANIS 9 years ago
Dear Team
I need to make CIS sales submission and tried to do it by submitting the EPS as instructed in Guide.
But I received the following error message: "There were one or more validation issues that need to be addressed before this Full Payment Submission can be submitted to HMRC Authentication Failure. The supplied user credentials failed validation for the requested service"
What is the problem?
Thank you Dina
