Cost element 7000218 is not assigned to a cost component in CostCompStruct

Dear All,

How to change the standard price in MR21 for materials with Price Determination Control 3 ( header level V & 3) (Split level S & 3)

In MR21, when I am updating the price for initial stock uploading.

It throws me a error Cost element 7000218 is not assigned to a cost component in CostComp Struct 01

Actually the cost component structure 01 is not active. we are using OP cost component structure & it is active , further the assigned to the company code level.

Cost element 7000218 is assigned to the cost component structure OP.

please suggest why it result in above error, even though we are not using cost component structure 01.

Regards

Subbu.
