Employee resposnsibles Org unit Determination (Employee is assigned to Org Unit)

Hi ,

We want to determine Org unit based on employee responsible but not on basis of USER.

Employee responsible will be assigned to a particular position in Organization .

We want to determine Organization unit where Employee is assigned .

When in transaction Partner Function employee responsible is selected then Organization unit to which employee is assigned should get determined.

When employee resposnsible is changed Org unit (Service ) should change .

Please suggest solution.

Thanks & Regards,

Anup Reche
