Stock Aging Report using Bin Transfer date instead of receipt date


Does anyone know why the Stock Aging Report uses the STK-STK date for inventory age, as opposed to the receipt date?

I noticed that the inventory age for some parts is getting overwritten if the stock is moved to another bin via Inventory Transfer.

Part ABC is purchased and we receive qty 10 on 1/1/2020 to Bin1.
Parts stay in Bin1 until 6/1/2023, when the full qty is moved from Bin1 to Bin2.
Running the Stock Aging Report shows that part ABC has qty 10 in Bin2 with a date of 6/1/2023 instead of 1/1/2020.

Is this how the Stock Aging Report is supposed to work?

I tried adding a new Stock Provision Format Code, but when I select “Aging” as the type, it greys out the transaction selection options.

Lot tracking would solve this, but our parts in this company are not lot tracked and I don’t think it’s feasible to implement at this point.
