Have you noticed changes in the P41202 - Summary Availability program after upgrading to A9.3?
Prior to A7.3C12, P41202 – Summary Availability would display items / locations when there is only quantity “On Receipt”. (On Receipt quantity is the total number of items on receipt for a specific location. The total is based on the total number of items entered in the Quantity on Purchase Order Receipts and the Quantity on Work Order Receipt fields.)
This would happen regardless of the setting in the P41202 PROCESS CONTROL processing option which states: Enter a '1' to omit locations with no quantity available. If left blank, all locations will display.
