Calling a submap

Use the Call Existing Submap wizard to call a submap. The submap must already be in the workspace.

If a submap does not exist, use the Create New Submap menu option to create a submap that you can call. 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.

The following steps describe how to call a submap:

  1. In the Broker Application Development perspective, open the calling map.
  2. In the Source and Target panes, select one or more sources and one target. Any of the sources or the target can be a wildcard, an element, or an attribute.
  3. Click Map > Call Existing Submap. The Call Existing Submap wizard opens.
  4. Complete the wizard, following the on-screen instructions.
The call to the submap takes the following FORMAT:

Only source parameters appear in the call and only message parameters appear in the list.
