The Self Invoice Numbering Rule is not working and the numbering rule which is set is not effective for the supplier invoice documents.
Reproducing the Issue
- Go to Supplier Invoicing work center
- Select New Invoice Without Purchase Order
- Enter the details
- Select Save
The Self Invoice Numbering Rule will be active only for ERS (Evaluated Receipt Settlement) Invoices and no other type of invoices. As a result, the Self Invoice Numbering rule maintained in Document Numbering Formats for Supplier Invoicing under Business Configuration is not picked up.
This is the standard system behavior.
You need to create an ERS invoice with relevant Reverse Charge Mechanism (RCM) tax codes. For these documents, an Official Document Number (ODN) is generated, based on the GST registration number and the annual year.
Note : All existing ERS invoices should be posted before creating the document numbering rules for self invoices. This will avoid mismatch in the document numbering format.
