select from itab not possible

[mem1b]

Hello

I'm at the https://exercism.org/tracks/abap/exercises/itab-aggregation and solved it with a select from itab.
But ran into the following error:

Code:

  METHOD perform_aggregation.

    SELECT
      FROM @initial_numbers as a
      FIELDS group,
             COUNT( * ) AS count,
             SUM( number ) AS sum,
             MIN( number ) AS min,
             MAX( number ) AS max,
             AVG( number ) AS avg
      GROUP BY group
      ORDER BY group ASCENDING
      INTO TABLE @aggregated_data.

  ENDMETHOD.

Copied the testclass to my local class on a 7.55 Release and there was no issue:

Guess at the moment there is no downport for this case.

thanks, yea, its a bug, not supported yet

in order to support FROM @itab fully, the runner will need a database connection, just like in normal ABAP

for performance reasons, we probably dont want to startup a database for each exercism ABAP run
