Finalization of a personal account (warehouses)

In your personal account, you can display the number of goods in stock (in goods) [file]13836[/file] it is necessary to evaluate the revision in order to be able to display 1 more column that would show the availability of goods in a certain warehouse MINUS positions that are in certain BP and statuses That is, for example: Warehouse "X" has 10 pairs of shoes So you need to display in the new field = 10 But if we specify in the settings that we need to check certain statuses in certain BPs Then in the table you need to show the balance minus the number of positions that are in these stages - the setting should be a multilist so that you can select several options for bp and statuses And if in these statuses (for example) there are 5 pairs of the same shoes, then only 5 should be displayed in the new column Since this will be the remainder minus the count in the selected processes How many hours of improvements will it be?
