Cash Advance For Travel Management (TRIP)

Hi All SAP Gurus,

I have problem in settlement of TRIP in Travel Management. The problem is when a TRIP is created and cash advance is been paid to the employee while settlement of the TRIP the cash advance is not getting deducted from the total expenses been incurred during the TRIP. It show the Employee Vendor account balance with the total of cash advance added to it. Please help me in this I need to configure the cash advance been deducted from the settlement.
