Include a list identifier with the classification code

Error FX-SCH-A-000296 Factur-X

Attribute '@listID' is required in this context.

Mandatory rule: As long as it is violated, the invoice is invalid and will be rejected by validators.
What is wrong

What the rule means

The list identifier states which code list the classification code belongs to. Without this attribute, the code's list association is not fully specified.

Please add the list identifier to the classification code

What to do
  1. Locate the affected ram:ClassCode in DesignatedProductClassification.
  2. Add the listID attribute to the element.
  3. Regenerate the invoice and validate it again.
