Confirmation regarding the TRIP t code in HR Module

Hi Friends,

First,I would like to say about my requirement.

This is a HR Module where we have the workflow for the service Manager Expenses Approve.

In this the Manager Decision step has got three options(Workitems in workflow)

1.Approve Expense Request:

2.Approve Expense Request with change:

3.Reject Expense Request:Manager will be able to reject it from backend side.

Whenever the manager selects any of this workitems,the transaction code invoked is PR05 in the As-is Scenario.

But in the To-be-Scenario,the transaction code should be TRIP

instead of PR05 and the Manager decision step 2.Approve Expense Request with change should be changed to 2.Review/Change Expense Request where we use TRIP T code and the BAPI used is TRIP_CHANGE_INTERACTIVE to trigger the TRIP T code.

According to my Analysis we use the method 'Change Interactive' where the BAPI 'TRIP_CHANGE_INTERACTIVE' is used and is present in the Business Object BUS2089.

I wanted to know whether iam going right or not.
