customize i-expense account generator to trigger from LINE DFF

Hi,

We used oracle hook AP_WEB_CUST_ACCT_PKG to populate account segment values as per our custom requirement. They are based on the project code (DFF attribute in Lines Details Level). The custom hook logic is working when we do straight expense report. But when we change the project code (DFF attribute at Line Details level) to some other project, and go to NEXT and NEXT (I-Expense report navigation), the new project related segments (as per Custom hook logic) are not getting populated in Distribution tables. We want the a/c generator to get kicked of either when we moved from 2 to 3
