Now, when we use the data transform, the properties appear in the grouping as designed in the application. i.e. if there is an embedded page "CustomerDetails". All the properties inside the embedded page (FirstName, LastName etc) appear as items in the "CustomerDetails" folder. Now, is there a way we can show the properties without any folders so that the data explorer shows a flat list of properties?
If we can show them in any custom folders (i.e. we can show any property inside any folder we want. Ex: FirstName and LastName appear under a folder "CustomerName"), it would be ever better.
Unfortunately currently there is no way to show the properties as a flat list? This could be an enhancement to the product. The best thing to do is to have your Account team initiate a conversation with Pega product management to evaluate this with respect to feasibility, risk analysis, timeline for delivery etc. We can certainly help you with the creation of an enhancement request, let us know if you need help with that.
