According to expense administrator role can not check the mapping between cash advance number and expense line before posting. Sometimes there may be an incident where the employee is mapping wrong and the system cleared advance incorrectly. It is hard to adjust the transaction when the system cleared incorrectly more than one advance and the advance request/expense report has many approval.

I want to suggest the idea to make expense administrator role can see the cash advance mapping detail likes they can see the expense in all expense report page. So, they can check the detail before posting the transaction.
