Hi Rakesh,
The name of personnel action sound confusing, you can name it as per the requirement and configure accordingly. Employee will be on international transfer and comes back after some time later. So, if there is any personnel action on transfer or something , create a new reason code as ' International transfer' and process this action for these group of employees. Also you need to configure another action called return to base or something or assign a reason to an existing action as 'return to home' or something. For one of my clients it was defined as 'leave of absence action' with reason code as 'International transfer' and 'return to work' with 'reason code' return to home country'. These two actions performed on these employees. As per business requirement configure it and process.
Thanks
Madhav.
