How to extend team calendar level subordinates to manager

Dear all,

Upon go-live our company has decided to use standard SAP ESS/MSS config. However after 3 months of implementation

our manager has problem to see staff absences using team calendar. Current standard ESS/MSS allow manager

to see all the staff under his organization only.It means the manager only can see one level sub-ordinates staff.

Now, we have decided to allow manager to see 2 level of subordinates.Appreciate your assistance to help me to config this

since I have no idea at all about ESS/MSS. TQ
