If an Informatica Platform 10.x application includes a mapping that uses parameters, you can configure Metadata Manager to use the parameter values when you load the resource. Metadata Manager can use parameter values that are defined in a parameter set. Metadata Manager cannot use parameter values that are defined a parameter file.
A parameter set is an object in the Model repository that contains mapping parameter values. These values override the default parameter values that a Developer tool user configures for objects within a mapping.
Metadata Manager can use parameter values that represent the following objects:
Connections, table owner names, and table names for relational sources, targets, and lookups
Names and directories for flat files
You assign parameter sets when you create or edit an Informatica Platform resource.
Assign parameter sets based on how the mapping is deployed within the application. If the mapping is deployed directly to the application, you assign the parameter set to the mapping. If the mapping is within in a deployed workflow, you must assign the parameter set to the workflow. The parameter set applies to all mappings within the workflow. You can assign a parameter set to one or more mappings or workflows.
Metadata Manager uses the parameter values defined in the parameter set to display the mapping objects and to display data lineage. If a mapping uses parameters and you do not assign a parameter set to the mapping, Metadata Manager uses the parameter default values.
