Capacity availability check does not match evaluation

Hi All,

i'm using capacity availability check during production order creation, overall profile selected as per sap help: SAPSFCG012.

During this check inside production order requirements shown in finite scheduling differs from results in can see in CM01 with overall profile SAPSFC010.

In CM01 requirement hours are smaller then in capacity check in PO.

Please advise what could be a root cause.

Also, is there a recommended profile for capacity check inside production order and for evaluation?

Thanks,

Andrey
