Hello Sandeep,
You have maintained any Assembly Scrap and operation scrap percentage in material master,
In Routing picture you enter the scrap 2 as percentage in each operation,
and you got the scrap Quantity is 6.27
6.27 is quantity not percentage
Please also refer below document of scrap variance
SAP Library - Cost Object Controlling (CO-PC-OBJ)
Please check and revert
Thanks & Regards
Umesh Mali
