service order internal activity cost were not calculated
Hi, I created one service order in iw31 t.code, in this order i entered work center , activity type, work duration. but i am not getting the internal activity plan and actual cost. I am getting the only external plan and actual cost.
I maintained the activity price in kp26, i assigned the cost center to work center. Some times in service order level i am getting the below error:
Missing work center formula,
Any body please tel me the work center formula steps in each tab wise for service
Thanks & Regards,
