Use a local catalog in conjunction with Drag and Drop to drag down data set items from your mainframe, edit them and then move them back to the mainframe or to your testing environment.
Configuring a local catalog
A local catalog is attached to an enterprise server, and so you can associate one or more of your mainframe subsystem projects to the server in order to utilize the contents of the local catalog.
Local catalog filters
Local catalog filters enable you to focus on the specific information required, by displaying only those items in the catalog that match the search criteria of the filter.
