3499246 - Incorrect Numbering Format Pick Up While Creating New Supplier Invoice For a Company

System picks incorrect numbering format while creating supplier invoice for a particular company. 

SAP Business ByDesign

1. Go to Supplier Invoicing work center
2. Go to Invoices and Credit Memos view
3. Select the relevant Invoice
4. You can see that, numbering format is different 

You have activated the numbering rule for self invoices and Self-Invoice/ERS is marked as Yes. You can define the tax registration number for Self Invoices and not for regular invoices. 
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.

Note - When you copy a self invoice, the document numbering rules will not be applicable, as the invoice is treated as a normal supplier invoice.

If you do not use the self invoices, you can delete the current numbering format and try to create a new rule with out tax registration number. Later system will create an invoice with proper prefix.
