Issue: We are experiencing an issue with Malaysian E-Invoicing submission where NRIC numbers need to be used instead of BRNs for specific suppliers when submitting self-invoices. Despite exploring multiple configuration options, the system continues to default to BRN values.  

Context: If we buy from a private individual in Malaysia we have to submit a self-invoice with an NRIC number. 

As checked, the NRIC can be used in Sales invoice, we hope that NRIC node will also be added to Self-invoice.
