To use processing mappings in PowerCenter workflows, deploy all request files created with the processing mapping wizard. To deploy request files, copy or move them to the PowerCenter Integration Service source file directory. The $PMSourceFileDir service variable configured for the PowerCenter Integration Service process specifies the source file directory.

You access the request files when you create the send request workflows. When the send request workflows run, the PowerCenter Integration Service reads the appropriate request file from the PowerCenter Integration Service source directory.
