Return value obligatory for loops?

[rdiger_plantiko2]

Hi - I want to write a loop expression that doesn't yield a return value nor an action. It is simply a loop. It seems, however, that I am forced to choose either of these options. So I choose the proposed "Return Value" "Action". But it's confusing, since this "return value" is not populated and not intended to be populated. How to avoid it?

For Expression return value has to be assigned. you can't avoid.

You could assign same input loop table or if possible Function return data object or create a 'No Result' ruleset variable.

You may also assign a default object from application FDT_SYSTEM such as TEXT or BOOLEAN.

In the rule you can define that the expression will be called but the result will be ignored.
