(Add User Acceptance State) business rule

If a user closes a case, the system changes the state to "Awaiting Acceptance" via (Add User Acceptance State) business rule below:

Once the case state transitions to "Awaiting Acceptance" there is an OOB Workflow that is attached by business rule (Trigger Awaiting Acceptance Workflow).

This business rule is designed to notify the user to review and accept or reject the resolution or reopen the case if needed. If the case is accepted, the state changes to "Closed Complete". If there is no response within two business days, the case closes automatically. If the user rejects, the workflow is designed to place the case state into "Work In Progress".
