Hi,

In this article, I will explain the usage of Display Business Rules and g_scratchpad with 1 small requirement

Requirement: When creating a new problem task from Problem view i want to populate few fields of problem into the problem task such as Assignment group, Assigned to, problem statement.

So For this, we will create a Display BR on the problem_task table. The Display Br executes whenever we view a record on the problem_task.

Display BR

System Definition -> Business Rules ->New

Table: Problem_task

conditions: Parent is not empty (So that this BR runs only when click on new from existing problem)

Under Advanced, in the script add this code

(function executeRule(current, previous /*null when async*/ ) {
    var gr = new GlideRecord("problem");
    if (gr.get(current.parent)) {
    g_scratchpad.parent=current.parent;
        g_scratchpad.short_description=gr.short_description;
    g_scratchpad.assigned_to=gr.assigned_to;
    g_scratchpad.assignment_group=gr.assignment_group;
    }

})(current, previous);

Save the BR.

Then create a onLoad client script and there you will have access to g_scratchpad object and populate the values into the problem_task form.

Client Script

function onLoad() {
   //Type appropriate comment here, and begin script below
    if(g_scratchpad.parent) {
        g_form.setValue("short_description",g_scratchpad.short_description);
        g_form.setValue("assignment_group",g_scratchpad.assignment_group);
        g_form.setValue("assigned_to",g_scratchpad.assigned_to);
    }   
}
