2749504 - MDG UI: Error message when assigning an already assigned plant to a different supplier/vendor

On MDG UI supplier Control Data UIBB, when you assign a Supplier with a plant which is already linked to another Supplier, there is no error shown on MDG UI. Due to this, the CR can be submitted and approved, but the assignment of the plant to the Supplier will not be saved after Change Request activation. If the same action is performed on SAP GUI transactions like XK02, there will be an error shown as "Plant xxx is already assigned to vendor xxx" which prevents the change.
