Posting only possibel in "0008" storage location

Question

Dear all
I am procuring material against cost center , i have used K and G/L acounts in PO, but during GR it is throwing the above error. Posting only possible in "0008" Sloc. i have not assigned any sloc in the po also as it is not required, because during GR the procurement will be consumed directly against the cost center.
Please guide
Sam

Go to Transaction SE24
Enter the Object Type CL_EXITHANDLER and click on Display.
Double Click on method "GET_INSTANCE".
Put a Break-point on 
Call method cl_exithandler=>get_class_name_by_interface
Run any Transaction for which you need enhancements.
The execution will stop at the break point. Check the values of variable 'exit_name', it will give you the BADI name called at that time.
