Hello Friends,

For example, when you validate invoice and this error occurs then follow this step.

First, you have to click debug mode then Go to Accounting -> Journal (customer invoice journal) -> Next number (INV sequence). Click it. you will see sequence that is your sequence size and from to date with next number   table. So, look that table, there is from when to when date limit and limited sequence numbers. You have to change there for your error.

Thank you

You can use OCA Renumbering module. After installation just run it. An dthe problem is solved.

Check Vendor Bills -> Other Info -> Journal -> Entry sequence.
