DataSource: PageName as well as Parameter name
PRPC automatically creates a page called 'DataSource' for the integration layer in the response data transofrm while configuring REST connector via wizard. The DataSource page is used to reference/fetch the property values from the integration layer to the Update Primary page as 'DataSource.response_GET'
In addition to creating the page called 'DataSource'. PRPC also creates the Parameter with data type page? Is there an explanation what PRPC creates the parameter called 'DataSource' for?
