how to track the transactions from Non receivable begin balance amount in the reconciliation report

Summary

Determine the transactions from Non receivable begin balance

Content

There is an amount showing in the non receivable begin balance line in the receivables to ledger reconciliation report. However we cannot drill it down. Report returns no data.

According to Oracle Docs, it only shows for the current fiscal year. But we need to determine the amount showing in there.

Is there any way we can determine those transactions that's causing the balance?

Thanks!
