Receipt number is not displayed in cmr_rcv_transactions table in Accrual Reconciliation report.

We are developing a custom report which is a xerox of standard Accrual Reconciliation Report. Our client requirement is in below transaction types they want receipt number to be populated. But receipt number is not populated in standard table for the below.

1) Standard
2) Credit
3) Accrual Clearing
4) Accrual Clearing reversal
5) Trade receipt accrual
6) Trade return accrual

Understand Oracle will NOT support custom reports

What we want to understand is, under what scenarios receipt number will be populated for above transaction types?
