Hi Archana,

thanks for reporting. This is expected behavior as under the expression, we
only list data elements/attributes which value type is possible to
aggregate. This means basically numeric value types. The expression will be
evaluated to a number, hence this rule (e.g. 5 x 2).

The filter will be evaluated to a boolean (true or false) (e.g. Gender ==
'Male'), hence we allow all value types there.

Hope this explains it.

regards,

Lars
