Hi Naveen
If your GR and GI (Backflush) happened at same time, there is no Question of WIP in a PCC scenario
WIP is only possible when you use Reporting Points and issue the Components earlier than GR
Just check for your PCC, it should show GREEN Status with Zero WIP Amount (If you are not using Reporting Points).. It should not show anything RED
Formula for WIP At Target cost is: Yield Confirmed at operations / Reporting Points, but GR Not yet posted, is multiplied by Std Cost
Variance: Actual Cost - Std cost of GR - Std Cost of WIP (If Any) - Std Cost of Scrap (If Any)
