scalable tick on Batch order formula lines

scalable tick on Batch order formula lines …how its function?

If scalable and you need 1 to make 1 parent and you make 10 parents you need 10. If not scalable you need 1 to make 1 and 1 to make 10.

yes… but do it function at batch order level also?

The point is that it is at batch order level, you load the 10 in the batch order, and the requirements depend upon whether the line is scalable or not.
