Purchase order changes after GR & invoice
Presently system is allowing users to make changes in purchase order qty, values even after making of GR & Invoice.
How to control that, once GR or Invoice is done system should not allow users to make any changes in the purchase order qty and values..etc.
For the PO Release strategy is configured & Release indictor is set 1. User are Derelease the po & do the changes.
Kindly suggest the configuration flow for this requirement.
Thanks in advance
