When you add a reusable transformation with transformation parameters to a mapplet, you can set the instance value for each parameter. The instance value of the parameter is the parameter value in a specific mapplet.
After you add the transformation to a mapplet, set the instance value on the transformation
Parameters
tab.
Choose one of the following options for the
Instance Value
:
Expose as mapplet parameter
Create a mapplet parameter with the same attributes as the transformation parameter. Bind the mapping parameter to the transformation parameter in the same step.
Parameter
Bind a mapplet parameter to the transformation parameter. You can browse for and select a mapplet parameter to bind to the transformation parameter. You can also create a mapplet parameter and bind that parameter to the transformation parameter. When you create a mapplet parameter and bind it, you are performing the same task as the
Expose As Mapplet Parameter
option. However, when you manually create the mapplet parameter, you can configure a different name than the transformation parameter and you can set a different default value.
Use default
Use the default value from the transformation parameter. Skip binding a mapplet parameter to the transformation parameter.
Value
Enter a different default parameter value to use in the mapplet. Skip binding a mapplet parameter to the transformation parameter.
