Duplicate Checks

The duplicate check for a transaction is done during transaction processing if the Duplicate check is applicable for the Source. Payment fields marked for duplicate check in Source Maintenance are matched with all the payments booked within the duplicate period. The booking date of the payments is considered for evaluating the duplicate period.

The duplicate period is considered based on the number of days maintained for the source. If the maintenance is not available, then the duplicate check is not done.

If there are any matching payments with the fields identical with the payment being processed, then the payment is moved to Business Override Queue (PQSOVRQU) for further investigation.
