WIP and Variance Calculation

Hi,

Can we calculate WIP and Variance calculation for the same process order? As I understand if Proceess orders status "DEL" then WIP is Zero value.. for same order I am able to see some variance..

a) Is it possible to Calculate WIP(without zero values) and Variance for same process Order?

b) How can we update target cost this should be populate in Variance Calculation(KKS2). (for this done updated price,costestimate,mark and realeased.. its been updated in Material Mater.. but not showing in variance calculation as target cost)

C) what are the pre-requisites require to do WIP(with values) and Variance Calculation. for the same process order.

Appreciate you valuable inputs.

PS: we are not doing overhead calculation(KGI2) for cost sheet.

Thanks

Srinu
