Why this error occurs
The element is mandatory in this standard but is missing or empty in your file. Typical causes: the field is not filled in the invoicing software, the ERP export does not map it, or the element is present but contains only whitespace.
How to fix it
Add the element with a non-empty value at the position given by the context above. Check the master data (seller, buyer, payment) in your invoicing software; most tools expose the field under the business term name shown here. Re-validate after the change.
