On the System > Data Retention Management page lets consider we decrease the number of days of the "Finished Transaction PII Data (days)" field from 200 to 100. Due to this change lets assume 10,000 records will be flagged for deletion (data extracts, submission properties, xml history etc).
The core "Transaction Processor" service has the "Fetch Limit For Transaction Purging" parameter set to 500.
When I make the above change and click the Apply Policy button, how many records will be purged from the DB. Will the "Transaction Processor" config still apply so only 500 records gets purged on the button click?
