Hi @sanjana12 ,
If you want to create a list to use a schema other than the recipient table then check the Create or use a list with its own table option. Example, if you have broadLogRcp schema in query and to store the value in a list, you have to enable ' Create or use a list with its own table'
Whereas, If you enable 'Purge and reuse the list if it exists (otherwise add to the list)' option, each time the workflow runs it will delete the old records in the list and update the list with new values from the workflow. And If you disable the checkbox, then each time the workflow runs, new records will get inserted in the same list without deleting the old records.
