Mapping shows how parameters values are transferred from one activity to another
activity within a simulation process.
You can use maps to transfer parameter values from one activity to another activity while
the simulation process is executing.
By default, Process Composer creates mappings between activity parameters with the same name within a given
simulation process if certain attributes match (for example, type or input-output
relationship).
You can map activity parameters from the Dataflow panel.
You
can also use the Dataflow panel to create, import, export,
modify, or delete
parameters.
