Unable to search Purchase Order Number through Journal Drill Down

Summary:

We have a custom report where we can see the Journal batches coming from AP module and PO number if the AP invoice is PO matching.

The user can drill down from the Journals in Fusion and can see the AP transaction details. If it is a PO matching invoice, we can also see the PO number, Goods receipt number, SCM transaction type and so on. The report is fetching the data correctly. For one particular type of journal batch even if it is PO matching we cannot see the PO number and other details when we drill down through the Journals in Oracle Fusion
