My only doubt now is why the condition type ZVAT is in grey color,
We cannot edit ZVAT in Sales order.Currenlty in the line item condition tab,i add ZVAT with amount 5 and clicked enter,the value is getting updated but it is grey in color,i cannot further edit it.
I have maintained manual entry have priority.In the pricing procedure it is maintained as manual entry only,inspite of this why is it behaving like this.
