Message sent in Travel Management

Dear Consultant,

Assume four entities as 1) Traveler 2) Traveler's Manager 3) Travel Administrator 4) Travel Administrator's Manager.

Traveler's Manager is provided MSS. But Traveler is not provided with ESS. So the creation of trip request & approval is done on paper & thereafter Travel Administrator enters a Trip for the traveler in R\3. Here, the mail for approval is not expected to go from the System to anybody.

However the mail for approval is sent to the Manager of Travel Administrator which is irrelevant.

A002 is maintained between the (Traveler & his manager) & (Travel Administrator & Travel Administrator's Manager)

Suggest which relation is to be maintained with the traveler & Travel Administrator ?

Regards,

Bindumadhav
