I would suggest you to create a new custom field called Previous Assigned to so that you can determine who is the previous assigned to. so, when you click reassign the script can be

current.assigned_to = current.u_previous_assigned_to;

And, create a business rule to update this field when assigned to changes

BR: Before -- update

conditions: Assigned to changes

Script:

current.u_previous_assigned_to = previous.assigned_to;

when i write above script the below issue i am facing:

previous.assigned_to should not change everytime i update. it should only change for first time.

[amaradiswamy]

Then you can add condition to the business rule like

Assigned to changes and Previous Assigned to is empty

This will make sure the BR works only one time when assigned to changed for the first time

To achieve the assign and reassign functionality for your custom table in the scoped application, you'll need to configure the UI actions properly. Here's a step-by-step guide:

1. Create Two UI Actions:

   • Assign: This UI action should be linked to the "Assign" button. On click, it should allow the user to change the value of the assigned_to field.
   • Reassign: This UI action should be linked to the "Reassign" button. On click, it should assign the task back to the previous assigned_to user.

2. Define Conditions:

   • For the "Assign" UI action, you can set a condition that checks if the assigned_to field is not empty (indicating it's already assigned), and if it's not the original assigned user.
   • For the "Reassign" UI action, you can set a condition that checks if the assigned_to field is not empty and if it's not equal to the previous assigned user.

3. Scripting:

   • In the script of the   "Assign" UI action, you need to update the assigned_to field with the new user's value.
   • In the script of the "Reassign" UI action, you'll need to keep track of the previous assigned_to user (maybe in a custom field) before changing the assigned_to field back to that user.
