Expense Management Credit Card Vendor Setup

Hello,

I am trying to setup some additional configuration in Expense Management related to credit card reimbursements along with paying the employee

We are on 9.0 APPS and 9.1.3.1 TR

A little background on our setup.  Currently the employee (cardholder) is responsible for payment.  We were requested to add functionality to allow employee to select credit card payment or employee reimbursement when creating expense report detail.

I am trying to understand how to set up the address book record for main credit card account.  I understand each employee has a separate credit card number.  In my testing, the ach file created is not bringing in the employees credit card number so Citibank can apply correctly.  I do not see any remittance information linking employee card with payment information.
