How to create tolerance in Purchase order.. in version 13?

please let me know how to PO Tolerance it seems there is no such option in ERPNext13…please find me a way…

Please explain what do you mean by PO Tolerance. What is the logic you want the system to follow.

Tolerance means we are able to accept the PO delivery of such varience… Which means… If we give 5%

More than 5% or less than 5% of PO is not acceptable!!!

Check Stock Settings. There’s a field to allow Over Delivery/Receipt and set that as 5.
