GENERATE(

	var __stop = 'Table A'[Stop]
	return
	SELECTCOLUMNS(
		CALCULATETABLE(
			VALUES( 'Table B'[Stations] ),
			'Table B'[Stop] = __stop

Thank you for your answer, vivran22 

Unfortunately, this seems also to produce a full CROSSJOIN.

I'd need a CROSSJOIN grouped by column "Stations" (as shown in the example result table).

 

This should be possible with DAX, doesn't seem to hard! I just can't get my head around it.

This should be dead easy with GENERATE or GENERATEX.

      thank you so muchAnonymous !
      this seems to produce the table I was looking for! I don't think I would have come up with that solution, so "dead simple" maybe for you 😆

       

      thank you community!
