When you upload a file to DDCMS Direct, the system automatically checks for the following:
Correct file format - Must match BACS Standard 18 specifications.
Required fields - All mandatory fields must be present and in the correct positions.
Modulus Check - Validates sort codes and account numbers.
Valid processing dates - Ensures dates are acceptable for processing.
Assigned SUN - Confirms a Service User Number is included.
Complete bank details - Checks that all necessary banking information is provided.
Single originating account - Only one account per SUN is allowed per file.
📌Note: Files that don’t meet these criteria may be rejected. If you’re unsure about formatting or validation, please contact us via the Access Digital Assistant, and reference the title of this article. If a file does not successfully pass validation checks, an error message 'Validated with Errors' or 'Missing Processing Date' may appear and you will need to correct these to successfully submit the file.
