Use mapping parameters and mapping variables in place of values that you want to update without having to edit the workflow. You can include parameters and variables in any transformation that Data Integration supports.
The workflow XML includes the default mapping parameter and mapping variable values. You can edit the values when you configure the task or override them with values in a parameter file.
You cannot add or delete parameters or variables from the PowerCenter workflow in Data Integration.
If the workflow uses a parameter file, the parameter file name is uploaded with the workflow. Copy the parameter file from the PowerCenter directory to a location that is accessible by the Secure Agent or to a cloud-hosted directory. Also, you must update the parameter file headers to use the Data Integration project and PowerCenter task names. For more information about parameter files, see Mappings.
