scan Employee bank data against Supplier bank Data

Currently using PeopleSoft HCM (PUM 48) / Tools 8.59.
Would like to hear what other PeopleSoft customers are using(techniques / process etc.) to scan Employee bank data against Supplier bank Data for audit purposes.
Intent is to analyze the data to confirm Employees are not set up as Suppliers.
The ask is to validate the employee HR bank information against the Supplier data.
Since HR bank details are confidential we dont want to expose this confidential data, but analyze the data within the HR environment to produce an exception report.
