Step 2. Use a Mapping Parameter

Step 2. Use a Mapping Parameter

After you create a parameter, use it in the Expression Editor of any transformation in a mapping or mapplet. You can also use it in Source Qualifier transformations and reusable transformations.
In a Source Qualifier transformation, mapping parameters appear on the Variables tab in the SQL Editor. Use the following rules and guidelines when you use mapping parameters in a Source Qualifier transformation:
  • Enclose string parameters in string identifiers appropriate to the source system.
  • When necessary, change the format of the datetime parameter to match the format in the source.
You can also use mapping parameters in the Expression Editor. When using mapping parameters in the Expression Editor, do not enclose string parameters in string identifiers. The Integration Service handles parameters just like any other port identifiers.
Use mapping parameters in reusable transformations.
You can also use mapping parameters in transformation overrides in the session properties in the Workflow Manager. You can override properties such as a filter or user-defined join in a Source Qualifier transformation.
