I created one real internal order (IO001) with responsilble cost center as 110001.
But when i created settlement rule for the above internal order (IO001), I was able to enter another cost center as receiver. I entered cost center as 120002.
System didn't checked if settlement receiver cost center is same as responsible cost center in internal order.
Please help me and let me know, if we can bring this control in standard functionality or some exits. If it can be done through exits, please let me know details of exit..
