[hiddendragon]

Hello everyone.

I have question.
I try to calculate overhead rate for material 63003007701-07 (valuation class FINI)
by tcode CK11N

in tab costing data.
there are 4 line for Overhead.

so I check in SPRO
Controlling -> Product cost planning -> Basic setting for material costing -> Overhead -> Define costing sheet

I choose costing sheet as show in CK11N
but I donot know what base for material ?
how do I know that each material calculate use what base ?
