3815560 - How can I find transactions made prior to card assignment?

I want to find the transactions that are not visible in Available Expenses and were made prior to user's card assignment. I was expecting some transactions to populate in the user's Available Expenses but those are nowhere to be found. The user was assigned a new card, but he received the physical card prior to the assignment and some transactions were made at the time.

Client would like to find the hidden transactions that were incurred before the corporate card was assigned to the user. , KBA , CON-CA-USP-CRC , Credit Cards , Problem
