WIP Calculation

Dear All

I am calculating WIP for a production order and settling it to FI. After this, order is made TECO, after which variance is calculated and settled to price difference account.

But after variance settlement, when I revoke the TECO status and run WIP again, it is getting calculated, but the system is not allowing it to settle. Error - Status DLV/TECO was reversed after settlement of period 004 2012 is coming.

When I change the status back to TECO after calculating WIP, system is allowing to calculate variance, and on settlement, the WIP amount is getting posted as variance in Price difference account. No WIP (Inventory) A/C is getting affected.

Pls advice.
