Data Quality Mappings and Workflows in Data Integration Hub

You use Data Quality mappings and workflows in Data Integration Hub publications and subscriptions with custom mappings.
In publication mappings, the source is the publishing application and the target is the Data Integration Hub publication repository. In subscription mappings, the source is the Data Integration Hub publication repository and the target is the subscribing application.
You can use user-defined session parameters in custom workflows and define their values in Data Integration Hub or in a parameter file. You can manage the values of user-defined session parameters in Data Integration Hub in the Forms Designer. You cannot manage the values of built-in session parameters in Data Integration Hub. For more information about session parameters, see the section "Working with Session Parameters" in the PowerCenter Advanced Workflow Guide.
Note: To use Data Quality mappings and workflows to publish files with file transfer, session parameter names must start with $InputFile_.
