Hi Team,

Greetings!

We have to retain some of the employee records even when they are moving out of the company to perform MSS activities for direct reports i.e. they are not actively working in company and have moved to different company but they need to be available in source company for a certain duration to continue MSS activities as they were doing earlier for their direct reports.

Requirement

Source Company =A

Destination Company =B

Person Name = Amber Smith (just an example)
