Throw Error when Plants are different in Component Tab in Tcode IW31 IW32

Hello Experts,

Please help me in finding out an EXIT or BADI wherein i can restrict the user from entering Different Plants in Components TAB while creating Order using Tcode IW31 or Changing Order using Tcode IW32.

The restriction would be based on the Order Type and if the Order type lets say 193M.

So Please guide me in resolving this issue.

Thanks.
