Regarding KOFK in Account Determination

Dear Friends,

I have configured Rental Contract document Type ZMV (Copy of MV) with item category ZMVN (Copy of MVN) . I created a contract using VA41 using material type ZDIE (Copy of DIEN) . When I try to save the contract, system gives me an error as "No G/L account found in Account determination type KOFK" for the condition type in the pricing procedure . Why is KOFK getting determined . Any solution . How do I change this to KOFI .

Kindly help
