3607660 - Approval Process for Travel Expense is not working as expected.

You notice that to be able to have the expected approver for a new expense report, you need to edit the cost assignment and input the cost center again.

SAP Business ByDesign 

1. Go To Work Center Travel and Expenses.
2. Go To New Expense Report on Behalf.
3. Create a Expense report for employee ABC(ABC represents the employee).
4. You will see that the Approver will be DEF(DEF represents approver) which you believe is incorrect as per definition of the approval process.
5. Now in the expense report, Go to Edit Cost Assignment.
6. Add a row, select Account Assignment Type "Cost Center" and Enter XXX(XXX represents the Cost Center ID).
7. Click ok.

Result: Approver changes to MNO(MNO represents the approver) which is as per definition of the approval process.

When the employee who is creating the expense report is an approver himself, the initial approver will be himself.
When the details of the expense report are edited, then the system determines the approver from the list of approvers maintained in the system.

This is the current and standard behavior.
