For example, if you know that you want to use all fields that begin with SALES_, you might declare the macro variable fields as follows:

Macro variable name: Declare_%salesfields%
Macro variable fields: {"SalesFields":"Pattern:^SALES_"}

Or, if you know that you want to use all input fields, you might use the following expression:

Macro variable name: Declare_%salesfields%
Macro variable fields: {"SalesFields":"All Ports"}

For more information about patterns, see the Mapping Architect for Visio documentation.
