When a preparation process has to run on the data that you want to publish before the source application publishes the data to

Data Integration Hub

,

Data Integration Hub

can trigger a preparation process before it runs the publication, so that the data that it publishes is always up-to-date.

When you configure a publication to run a publication pre-process,

Data Integration Hub

triggers the pre-process before it runs the publication. After the pre-process runs,

Data Integration Hub

runs the publication and publishes the pre-processed data.

The developer creates a PowerCenter workflow that runs the pre-process. You select the pre-process workflow and define pre-processing parameters in the Publication wizard. You can select a pre-process for both publications that use automatic mapping and publications that use custom mapping.
