Please note that Credit Notes and Debit Notes do not require a consolidated invoice as per LHDN regulations. Credit Notes and Debit Notes can be validated through the standard transmission process.
If you need to create a Credit Note or Debit Note after validating a consolidated invoice, you can follow the steps below:
Go to Customer & Sales, Sales Adjustments, Credit Note, Create Credit Note.
Tick update From Inv.
The system will auto-detect the UUID of the consolidated invoice.
