Unable to use HANA Decision Table in data preview or Calc View

I have created a decision table. The data foundation is a HANA table.

It activated okay.

I can see the stored procedure and execute it using:

call "_SYS_BIC"."DEV_JAN/DT_TEST2" (?);

That gives me the expected result, but:

- I cannot use the 'Data Preview' option, this is greyed out (as per screenshot above).
- More importantly, I cannot add the Decision Table to any Calculation View.

Now I did find note 2323175 which says

"Use of decision tables as a data source in calculation view has been removed" and

"Addition of decision tables with drag and drop has been removed"

So now I am completely stuck and confused about the above.

Does this mean I cannot use a decision table in a calculation view at all? Or can I only use it in a scripted view, by calling the procedure?

I have no problems creating and running calculation views without Decision Tables...

Thanks in advance for your help.
