You use the transformation to start a publication from PowerCenter. For example, if you run a publication pre-process workflow that prepares the data before the publication process can start, add the DX_Start_Publication transformation at the end of the workflow. PowerCenter sends a request to the

B2B Data Exchange

server, and the

B2B Data Exchange

server triggers the publication workflow that publishes the data to the publication repository.

If you use a PowerCenter parameter file, you can pass the contents of the file to the DXParameterFileContents port and use the parameters in the publication workflow.
