To call a submap, select it using the Call Existing Submap wizard. The submap must already be in the workspace.
Use the Create New Submap action to create a submap that does not exist, so that you can then call it. This action creates the new submap in the same folder as the calling map. It also allocates a default map operation name to the new submap. If the source or target in the calling map is a wildcard, a wizard allows you to choose a replacement element.
You can also map from a wildcard to a wildcard.
