Mass delete is a feature which supports deletion of multiple Jira configurations at once, e.g. Issue type schemes or inactive workflows.
As of now, the bulk delete operation just works for unused (e.g. unused field configurations) or inactive (e.g. inactive workflows) items in Jira.
What can be deleted?
The Bulk Delete operation is available for the following administrative items in Jira:
Inactive workflows
Inactive workflow schemes
Issue security schemes
Issue type schemes

If there are items to delete, they will be listed and can be selected for deletion. By clicking on the checkbox on the top, all items in the list will be marked.
Only items that are not in use can be deleted. They must not be part of any schemes or projects.
