Hi All, My purchase order number created as "PO436653223556". But this number format is too long. I want "PO43124" which is more shorter. How can I do that?

Setup > Company > Auto-Generated Numbers Purchase Orders > Allow Override = T That unlocks the PO number field so you can enter your legacy PO number for your data migration open POs. Make sure to fix the Next Number field on the auto-number page so that NS starts the sequence correctly with the next number. Because by default if you override the PO number, NS tries to re-start the sequence based on your override number.

Thanks for your replies @Koon Kabob But how can I reset this starting number? I don't see it is editable
