Besides debugging maps that are stored in local projects, you can also directly debug a map that resides in the server. Perform the following steps to do so:
Result: The Connect to WebSphere InterChange Server Express dialog displays.
Result: Map Designer Express displays a list of new maps on that server.
Result: The map opens in Map Designer Express in Read-only mode.
Result: When a breakpoint is hit on the server, you can step over or continue map execution, as usual. The resulting business object values will display in the Destination Test Data pane.
Result: Map Designer Express will close the map.
