Error in Retrieve Data Table Schema


When I run “Retrieve Data Table Schema” on a “TDAMemDataTable” I get the following error.



what version of DAD you are using?
can you create a simple testcase, that reproduces this case, pls?

I appreciate it’s three years later but I’ve just had the exact same thing and thought someone else might find this thread in future and benefit from it.

In my case, the service I was using wasn’t inherited from DataAbstractService. I was inadvetently trying to use a basic RO SDK service for data access which gives this error.
