“Layer Cost Worker” high number of Concurrent Requests

In the output of my Concurrent Processing Analyzer, there are a total of 560,261 records in FND_CONCURRENT_REQUESTS that are completed, and eligible for purging.

The “Layer Cost Worker” has 406,846, all of which is within the last 14 days.

Risk : IAW “Health Check Alert: Purge the eligible records from the FND_CONCURRENT_REQUESTS table (Doc ID 1095625.1)”

"If there are more than 500000 records in the FND_CONCURRENT_REQUESTS table, this can cause performance issues with the concurrent processing sub-system."

We have scheduled the Purge Concurrent Request and/or Manager Data – SYSOP-REQ_ID 14250729 > Age over 14 days.

Is there a way to setup to Purge Concurrent Request and/or Manager Data from just the "Layer Cost Worker"?
