The Manage workflow history lists provides the ability to create new SharePoint workflow history lists and enable existing SharePoint workflow history lists for use with Nintex Workflow within a team site.
A SharePoint workflow history list stores messages generated by a workflow. Everything from approval activity (approve/reject), updates to a workflow, comments, cancellations and even workflow errors.
By default Nintex Workflow creates a SharePoint workflow history list that is enabled for Nintex Workflow. The enablement deploys event receivers into the list for workflow reporting.
