Help: Duplicate Sales Invoice SINV-00001

I am not able to save quotations, invoices… kindly guide me. screenshot is attached

Seems like you have reset the number series for “SINV-” to zero. Please reset it to the latest number from Setup → Naming Series.

can you change the headline of your issue to something related to what problem you are trying to solve?
Doing so would make this potentially useful for others who might fave a similar problem. Now it’s only useful for yourself and that’s not the purpose of this forum I guess


ok sir. sorry for incontinence
