The default Match Set limit within Assure is set to 5000. The limit is set low to prevent over-processing of large volumes of Match Sets. When a match set limit is hit, the Assure control will throw the following error:
#UREC018: The match set generated by reconciliation task <task_name> exceeds the limit of 5000.
If more than 5000 Match Sets are expected, the limit can be adjusted within the Assure property files.
