When the system use the invetory profit/Loss accounts?

Dear all:

Hope you are doing very well.

When I run the inventory closing in AX2012 , the system post amounts to the inventory profit , inventory loss accounts. My question is when the system use these accounts? , note that I don’t have any counting or inventory adjustment transactions using the inventory journals , also i don’t use theses accounts in any transaction related to inventory. I use the WA inventory

I use the following transactions:

1- Purchase orders.

2- Sales orders.

3- Production orders (CW items with co-product production).

4- Movement journals.

5- Transfer orders.

Many thanks

If you cost at a site level and move it between sites impacting on the WA at a site level I believe it will then post to profit and loss, but you need to test it.
