@ServiceNow40 You need a Business Rule that triggers when the Assignment Group field (assignment_group) changes. The rule should store the previous value of assignment_group in a custom field called Previous Assignment Group (u_previous_assignment_group).

Hope you are using before update BR with similar to below code with enabling advance option:

// Check if the assignment_group field value has changed

if (current.assignment_group.changes() && !gs.nil(current.assignment_group)) {

    // Set the u_previous_assignment_group to the previous value of assignment_group

    current.u_previous_assignment_group = current.assignment_group.previousValue();

}

Hope this will help you.

Hello @ServiceNow40 

If working on form level then onChange client script is the solution.

You can achieve this with an onChange client script on the Assignment Group field. Here’s how:

1. Go to the Incident table and create an onChange client script.

2. Configure it to trigger when the Assignment Group field changes.

3. Use the script below:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }
    
    // Set 'Previous Assignment Group' with the old value of 'Assignment Group'
    g_form.setValue('previous_assignment_group', oldValue);
}

This will populate the Previous Assignment Group field with the previous value of Assignment Group whenever it changes.

Please hit like and mark it as an accepted solution.

Thank You
