What is the priority of Custom text1?

[LeeJaeYoung]

To prioritize in the schedule, put Custom text1 at the top and come out in the order of 1, 11, 2, 3, etc. What should I do?
Should I only do A, B, C, D?

The results of my testing
I think it's 1-9, a-z
Can't you do it with 11, 12, 13, etc.?

Archicad sorts these values character by character. It does not know that you want them to be considered as numbers.

What you can do is use the texts "01", "02", "03", etc. for numbers below 10.
