Can someone please tell me the significance of 'Lock/Unlock' button in Approval process.
I was just trying to create an Approval process on a Custom object as part of testing and did a very basic approval process. Once I submitted for approval and did all Approvals and now "Approval History" in related list Showing all change in status and can see the last status as "Approved".
But I can see "Unlock Record" on my detail page of record, I can able to Unlock it by pressing on it. But I couldn't understand the real scenario use of it. Can someone please help me to understand it correctly.
