0029·The note date is earlier than the original invoice

What this means

The adjustment must be dated on or after the original invoice date. An earlier date is chronologically impossible.

Why it happens

• The note was backdated to fall in a particular tax period.
• The original invoice date was recorded incorrectly.
• Timezone handling shifted one date but not the other.

How to fix it

1. 1Validate the note date against the original before submitting.
2. 2Do not backdate for period allocation — the adjustment falls where it falls.
