Abort action based on some value.

[asasas]

I have a field name "counter", which count the number of times a task is reassigned to another person using "Assigned to" field.

Based   upon counter value (say 3) i.e. if same task is reassigned more than 3 times to another person, it should not allow to change.

I got answer where in database it is not allowing to change (once I refresh the page) but in "Incident form " it is allowing i.e. it is reassigned to another person in "Assigned to" field.
I want to stop user from changing in "Assigned to" field also   .

I am using Business rule and my code is :

(function executeRule(current, previous /*null when async*/) {

  var counter;

  if(current.assignment_group.changes())

  {

  counter=current.u_counter=0;

    }

else if(current.assigned_to.nil())

  {

          current.u_counter=0;

    }

else if(current.u_counter>3)

  {

                gs.addInfoMessage("You excede more than 3 time   ! Now you cannot changed Assigned to field");

                current.state=previous.state;  

                gs.setValue('assigned_to', current.state);

            current.setAbortAction(true);  

            gs.setRedirect(current.state);  

  }

  else

  {

  current.u_counter += 1;

  }

})(current, previous);

Please help.

This assumes that your condition is: current.assigned_to.changes()

(function executeScript(current) {

       if (current.assignment_group.changes() || current.assigned_to.nil()) {
               current.u_counter = 0;
       }
       else {
               if (current.u_counter > 3) {
                       current.setAbortAction(true);
                       gs.addInfoMessage("This task has been reassigned more than 3 times. You cannot reassign it again.");
               } else {
                       current.u_counter++;
               }
       }

})(current);

Dear Geoffrey

My problem is I have to stop user from further selecting/changing (not allowing   more than 3 times) in the assigned to field

Code is working fine, but i have to stop user from further reallocating to another person.

That's exactly what the code does.

But you should really be handling it with a Client Script on the form. That Business Rule should stay there in case the Incident is updated from the List View.

To handle it on the Client-side, I would create a display Business Rule:

g_scratchpad.counter = current.u_counter;
g_scratchpad.assignment_group = current.assignment_group;

Then a Client Script that executes when Assigned to changes

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || oldValue == newValue)
       return;

   g_form.hideFieldMsg('assigned_to', true);

   if (newValue == '')
       return;

   var counter = parseInt(g_scratchpad.counter);
   var isSameGroup = g_scratchpad.assignment_group == g_form.getValue('assignment_group');

   if (isSameGroup && counter > 3) {
       g_form.setValue('assigned_to', oldValue);
       var msg = 'This task has been reassigned more than 3 times. You cannot reassign it again.';
       g_form.showFieldMsg('assigned_to', msg, 'error');
   }
}

The above Business Rule will then increment the counter when the form is saved.

I think you code will work, but i new to SN, so i am not getting where to write this code.

2nd code i am writing in client script but i am not getting where to write those two line of code(1st code)
