The Map Workflow Activity invokes a Blue Integrator Map.  This activity is towards the top of the Activity Palette in the Blue Integrator Workflow Designer.

To use this activity in a Workflow, you must set the InboundMessage and OutboundMessage parameters, by selecting from the drop-down list of configured Blue Integrator Messages.  Note that the InboundMessage and OutboundMessage can be the same.

You must also select the Map property from the drop-down list of Blue Integrator Maps provided.

Optionally you can configure the Parameters property, to set explicit input parameters on the Map.  Each parameter can either be a constant value or bound to a Workflow or Message Context property.

On execution, the Message specified by the OutboundMessage property is populated by mapping the InboundMessage using the specified Map.
