I am currently working on an implementation project in a complex make to order scenario in which I am using valuated sales order stock.
For product costing perspective, I have created thee activity types FOH, Material and labour for product costing at sales order level. I used kp06 and kp26 with respective cost centres and cost elements. Please also note that we are not using COPA in this scenario.
After executing all the steps, it has been found that variance appears only in case of activity FOH, while there is no variance appearing in activity type Labour and machine in KKBC_ORD report.
