About this task

Breakpoints belong to the developer who sets them. Developers must set and remove their own breakpoints.

Note: At a specific line, you can set either a logpoint or breakpoint but not both.

Procedure

  1. Navigate to the server script to debug.

    For example, navigate to All > System Definition > Business Rules.

  2. From the Syntax Editor, select the gutter next to a script line.
