Workflow/Approvals

Hi all,

How can I do this scenario in AX.

We are using hierarchy in AX ( Managerial with option ) so :

User A1 has manager User B1

User A2 has manager User B2

However User A1 an User A2 have the same approver for their time sheet User B3. So User B3 is not part of the hierarchy and he is only approving expense for User A1 and A2.

How can I make sure that when A1 and A2 users are submitting their expenses, those expenses are going directly to User B3?

Thanks

no clue???
