Planned Order Processing 
In planned order processing starting from the MRP or MPS menu, choose Planned order → Create or Planned order → Change or Planned order → Display.
You reach the header of the planned order. From here, either when creating or changing, you can carry out a capacity check or, if necessary, capacity leveling. In display mode you can also carry out a capacity check. If there is an overload then the system branches to the capacity situation, that means that you cannot carry out any changes.
