Duplicate check functionality for Accounting Documents

[#1]

Hello SAP Team,

We have a scenario, where I need to check if Duplicate check functionality exists in Standard SAP, for scenario listed here. Reference number sometimes matches, while Vendor No & Amount always match. Entries are posted manually or through SAP JOBs. Does standard SAP supports duplicate check for this scenario? If yes - please help to provide details.

Thanks...

You can try to write the checking logic in T-code：GGB0
