The Parameter rule replaces the rules on a link with the rules included in the parameter you specify. When you create a Parameter rule, select the name of a parameter from the list of mapping template parameters.
The value of the parameter must be a set of rules that you want to use for the link.
The following figure shows how to configure rules with the same syntax on the Link Rules window:
The rules must be separated by semicolons (;).
Use a Parameter rule when the rules for a link between two transformation objects change from mapping to mapping. For example, you can create a parameter named $REPLICATION_RULES$ and provide the following value in the parameter file:
Mapping Architect for Visio expands the Parameter rule to separate rules and evaluates the rules in the order they are listed.
You can provide different parameter values for the $REPLICATION_RULES$ for each mapping you create from the mapping template.
Limitations
