Hi,
we are using EPESI 1.7.1 (unable to update because of a lot of customizations) with the premium warehouse module. I want to add a field in the Warehouse -> Items results view which shows the quantity of items available only in the warehouse that is selected in the warehouse filter on this site. Currently there is only a field which shows the total quantity (i.e. the sum, or quantity at hand) items across all warehouses, which is a bit confusing for users. Is there a simple way to add such a field?
I have already added a custom field and tried to add a new function in LocationCommon_0.php which should return the quantity of the item in the currently selected/filtered warehouse, but I am unable to get the correct result.
