What’s happening?
The many to one reconciliation matching rule does not work in the system under the specified module.
 
Reason:
This arises when the advanced bank reconciliation (ABR) matching rule is not performed based on a unique field, such as a reference number or description.
 
Resolution:
To resolve this, ensure that the ABR matching rule is performed based on one unique field, such as a reference number. Testing with the reference number for the trading party has been shown to resolve the issue.
