Hi Nikola,

I've just managed the reproduce exactly the same which produces and error in the MAL plan.

Seems like a bug.

Hi all,

I have several tables which represent different sources (sensors) of data. I want to find out which sensors picked up the signal first, and thus I decided to join these tables together, rank on common criteria and then select the first ones. However, that fails with:

Any ideas how to fix this?
