Job WIP Calculation

Hi,

I am trying to understand WIP Set up. When you post Item consumption for Jobs , two entries have been posted to G/L (Automatic Cost posting has been selected as yes). One is the Inventory Account and the other one is the Inventory Adjustment Account. My Assumption was when i calculate the WIP the Inventory Adjustment Account will get credited thus nullying the Inventory Adjustment Account. It is not happening this way. Is my assumption correct or what is the way of handling

When you run calculate WIP Cost system creates Job WIP Entries. Then you need to run Post Job WIP. System will Credit “Job Cost Applied Account” and Debit WIP Cost Account.

Thank you. I did the exercise with different WIp methods and now it seems to be clear to some extent
