In AP, you can do a credit entry (debit accounts payable and credit an expense account for example; but this cannot be done in expense management. That would be useful so those entering invoice requests into expense management could enter credits instead of the reviewer/approver having to wait until the invoice hits AP ,create a credit memo, and apply the credit memo.
This function would be very helpful in Expense Management. There are cases where both positive and negative values need to be allocated within a single transaction — for example, to apply credits or offset amounts due. Currently, the inability to enter negative amounts limits flexibility and often requires manual workarounds. Allowing this functionality would significantly improve accuracy and efficiency, especially when managing complex or exception-based expense scenarios.
