Unable to create a new Expense Claim with previously rejected credit card transaction lines

Hi,

I'm trying to assist a Proxy User in Oracle eBusiness Suite. She (let's call her Mary) had submitted an expense claim for someone (let's call him Ben). Ben rejected the expense claim. Mary deleted the credit card transaction lines in that expense claim and tried to create a new one. However, she received an error - Unhandled Exception. Please contact your Sys Admin. I have also replicated the error in a test environment. The aging report shows that the transactions are pending reconciliation. Mary is able to act as a proxy and create expense claims for other users.

Now, I tried finding the transaction lines in AP_EXPENSE_REPORT_LINES_ALL as I thought it could have something to do with WORKFLOW_APPROVED_FLAG. However, the transaction lines are absent in that table.
