Overriding Parameters Using the Parameter Hierarchy
Overriding Parameters Using the Parameter Hierarchy
When you create a parameter for a transformation, a logical data object, a mapplet, or a mapping, you can override the parameter by specifying a new parameter for the transformation, logical data object, mapplet, or mapping at a higher level in the parameter hierarchy.
For example, you create a parameter in a transformation. Then you add the transformation to a mapplet. You can either use the default parameter value from the transformation or you can create a mapplet parameter to override the transformation parameter value.
You can also override parameters using a parameter set or a parameter file. The parameters in the mapping use the parameters specified in the parameter set or parameter file. In a parameter set or a parameter file, you can specify only workflow and mapping parameters.
