COGS AS A COST ELEMENT ERROR

Hi all

While doing VL01N outbound delivery sales order not a cost object, am getting error message

M7093  field selection different for GL and movement type 601.

i know why the error comes , but in that GL cost center is option entry and wheras in movement type its suppress.

so how to do in that case ( GL created as a cost element and COPA is active)

could anyone throw some points to overcome that issue.

Regards

Raj
