WIP Calculation process

Hi,

I created the Production Order for 10 materials and end od the month i ran the KKAX and KO88 for productin order.

Some amount was posted to WIP GL Accounts with end of the month date.

In next month i confirmed the rest of the activities and i settled the order.

As per my knowledge whatever wip posted earlier to WIP should be reversed but in mh case those are not reversing.

Can you help me out what are the steps to do in process.

shall i have to run the Ko88 after KKAX not running of KO88 is not required for wip?

Thanks
