We have a service rest allowing external applications to create a child case in our application. The service REST activity perform some quick validation on the content of the request and then queues the request for processing in a dedicated queue with a snapshot of the request data as primary page.

In the QP-activity, I open the parent case and call pxAddChildWork to create a new child case. One of the parameters for this is DataTransform, which is a DT executed on the newly created Child case. In this DT, I want to copy some of the request data into the newly created child, but I don't seem to be able to pass the original request as a parameter to this DT. I could take the data by referencing hardcoded pyQueuePage.RequestData, but this is something I don't really like. Is there another way of passing the source page as some kind of parameter?
