Rollup is limited to100 rows

What does this exactly mean ? I tried to read learn more but couldn’t get

It means what it says. It will return no more than the first 100 rows from your relation.

Ok but if the column is not calculated from relation and it is a simple column then will it still work only for first 100 rows?

Here are most limitations explained

I’m a bit confused and was hoping you could clarify something for me. Based on the screenshot, will this problem occur horizontally (since there are multiple unitName values in a single row) or vertically, such as after around 100 rows when the matching starts behaving oddly?

Thanks!

The lookup array on each row will contain no more than 100 elements.

so the element shown horizontally (like in my case 3.OG App.31, 3. OG ..ect ect ) wouldn’t show more than 100 element?

Correct

Thanks a lot
