When you create a customer invoice, the system generates an invoice number without preceding zeros.
Reproducing the Issue
- Go to the Customer Invoicing work center.
- Select New Manual Invoice under Common Tasks view.
- Fill all the mandatory fields.
- Upon saving, the preceding zeros are truncated.
For customer invoices, the system applies default rules and starts numbering automatically with the number 1 irrespective of the company or the invoicing document type .
However, the system does not allow to add preceding zeros. If you have a customer invoice with leading zeros followed by any prefixes, suffixes or separators, then the zeros will not be truncated.
This is expected system behavior.
