If you search the documentation for “Request Data Copier” you can find some context around the DPHs.
I don’t think a specific procedure is described for each DPH, a DPH is basically a filter, so you can also search on how to add filters to workflows.
It will go something like this:
1. Open the VSM in the Workstation
2. Select the Listen Step
3. Add a filter
4. Select Virtual Service Environment categorie, there is only one filter in there (the DPH)
5. From the Filter config, select “Request Data Copier” (RDC) in the dropdown list
6. In the RDC pane, select “meta” checkbox, add “request_meta_” in the entry field before <md-name>
7. Save the VSM, Deploy
