we have new std cost activation in Feb, 2021, then the Feb monthly comes big amount into rounding variance account, it is very strange, after my testing, the posting path should come from Stock management setup ==>Posting == > Standard cost variance == > Rounding variance.
1. As I checked, it should come from the subcontract production orders, because of service items is the FIFO cost valuation, but the FG/Semi FG is the std cost valuation.
2. Normally, monthly closing should be only 0.01 in voucher this main account , but now Feb is nearly 150,000, and March is nearly 50,000.
Did any expert know why this happens?
