Troubleshooting: Duplicate Invoice no

Question: why can't I save a new invoice? there is a message box prompted Document No. I-00003 is already exist in A/R Invoice.

Version: 1.8 / 1.9 / 2.0

Possible Reason:

Invoice no I-000003 is already exist in system. Thus, system wouldn’t allow duplicate invoice no to be created.

Solution:

You need to go to change next number to number which has not been used.

Go to General Maintenance > Document Numbering Format Maintenance; click on Category:Sales and select DocType:Invoice to edit. Change the next number that hasn’t been used in system and click on OK to save.

Now, you should be able to save a new invoice into system.
