AP Duplicate Invoice across different voucher styles

Oracle PeopleSoft

Version 8.59

Question: Hi- We are currently using both regular & amortization AP voucher styles. We had a duplicate invoice processed and paid One was paid as regular style - the other paid as amortization style. I understand that the duplicate invoice check functionality does not check across different voucher styles.

Are there any other ways to have a check completed across different voucher styles before an invoice is paid? Looking for both automated (would rather automated though) and manual ideas.
