Wrong stock out days calculations

Reproduce steps

1. Go to Stock on Hand Page and find any item which haven’t been updated for few months and its SOH = 0 (if there isn’t any make a physical inventory with proper date)

2. Make sure that the requisition template is calculated basing on stock

3. Initiate the requisition for the next period (after the last product update, in this case June 2017) - the SOH is calculated as a difference between the last and first day between this period, delete this form

4. Make Physical Inventory - make sure that you entered the 0 for tested product (I chose the 15.06.2022)

5. Initiate the requisition once again - the Stockout days changed to 15 what is the difference between the last day of reporting period and the day from the last PI proceeded in this month)

To do

1. Find exactly where the this calculation happens on backend

2. Fix the issue

3. On local machine make sure that everything is properly calculated

Expected behavior

If the product stock was 0 for the whole month the SOD should be displayed as a difference between last and first days of reporting period regardless the inventory was made or not.
