Is there a limit to the amount of values I can lookup? When I search for the topic I only get hits on the number of lookup fields you can have in a list.
I have tested this a bit and it was working with ~5600 items, but that was also with the list item threshold bumped up to 6000 (from 5000). Is it related to that threshold or not at all? I can't find any documentation on this topic and would like to know if I need to worry about it breaking over time with more records being added.
