Symptom. The invoice prints without a TIN, yet its e-Invoice status is Valid.
Cause. The e-Invoice was submitted (or imported from another system) while the debtor still had a TIN. The validated e-Invoice keeps its status even if the TIN is later cleared from the debtor record, so the invoice now shows no TIN.
Fix. Edit the debtor in A/R → Debtor Maintenance and reassign the TIN. The invoice then displays it again; nothing needs to be resubmitted.
