Substitute EXIT/BADI for Travel Plan Request(FI-TV)

Dear experts,

I am here to ask help for User exit/BADI with substitution function in FI-TV module.

I am using ECC 6.0 now.

<Requirement>

When the user save the travel plan request via TP04, set the field 1st Destination(FTPT_REQUEST-LOCATION_END) as "***EXPENSE***" if the field value is blank.

<My solution>

I use the enhancement FITR0003 to subsititue the value,

Source code:

Object:ZXTRVU03

IF TRIP_HEADER-ZORT1 IS INITIAL.

TRIP_HEADER-ZORT1 = G_CON_EXPENSE.

ENDIF.

<Issue>

I found the information of table PTRV_HEAD(General Trip Data) was updated.

However, what I want to is to update the table FTPT_REQUEST(Travel Plan Requests).

Does anybody know how to update it?

Thanks in advance,

Gary
