0026·Invoice reference number is required for a debit note

What this means

A debit or credit note exists only in relation to an original invoice, identified by the reference FBR issued when that invoice was reported. Your internal document number does not identify it.

Why it happens

• The internal invoice number was submitted instead of the FBR-issued reference.
• The original invoice was never reported digitally, so no reference exists.
• The FBR reference was not stored when the original invoice was submitted.

How to fix it

1. 1Store FBR's issued invoice number against every submitted invoice — you cannot issue notes without it.
2. 2Submit that reference, not your own numbering.
3. 3Only issue notes against invoices that were themselves reported digitally.
