Validation of the MDC submission

When you upload a file, our system will perform a number of validation checks on the data provided before adding anything to our records.

If the system identifies any errors with any service lines, an Error File will be generated. This will be available from the ‘Download a file’ section of the Employer Portal. It will list the individual service lines that have been rejected and provide a reason for the rejection.

Corrections should be made on the Error File and then uploaded to the Portal with an identical filename to that of the original file you received. These corrections should be made by the last working day of the month.

Further information about error types can be found in the MDC User Guide document (PDF, 1 MB).
