0064A note was already added for this invoice
What it means
FBR already has a credit note for this invoice and refused a second one.
Why it happens
- The first note was sent and accepted, and the same note was made again by mistake.
- You really need a second, separate correction for the same invoice.
How to fix it
- Open the invoice in this tool and look at "Notes on this invoice". If the first note shows an FBR number, it is already done.
- If you need another correction, check the FBR portal first. Ask your accountant or PRAL support how a second note must be made.
Based on our own sandbox tests. FBR can change its rules.
