Hi OF Team
I would like to inquire about the automatic numbering of objects. See this forum post.

I want the automatic numbering of objects to start at 100 and to be set in steps of one: So 101, 102, 103...

With a default value of math:max((parent()/pb/treenumber)+100)+1 it did not work. (Where pb is the parent entity and treenumber a number attribute.

With a default value of math:max(parent()/pb/treenumber)+101 it does not work either. The series 101, 202, 303 is created.

How to write the correct max:math code?

Thanks for yiur support

Dear Sabrina,
In your case you have to define 2 expressions:

  • in the first expression you should write math:max(parent()/pb/treenumber) + 1 and in Apply when specify count(parent()/pb) > 1
  • in the other one just write 101 in the Constant field.

Many thanks,
