OmegaAI Study Locking Mechanism

OmegaAI has a Study Locking feature designed to protect studies marked as "PRIOR" from accidental or unauthorized changes. This can be bypassed by specific trusted users with a unique User Access Control (UAC) privilege - Modify Locked Study.

What is Study Locking?​

When a study reaches the "PRIOR" status, it is automatically locked, making it read-only across the Worklist and Study pages. The lock is applied through a Workflow Step setting: PREVENT MODIFICATION>= PRIOR.

Note: The Prevent Modification workflow step mapping with Study Status is configurable.

Scope of Locked Study​

Modules Affected​

  • Worklist Page: All editable components are read-only (except for specific UAC-enabled users).

  • Study Page: All fields are non-editable when locked.

No Edit Button Behavior (Default Users)​

Users without the Modify Locked Study privilege won't see edit buttons, instead a lock icon is displayed.

Hovering over this icon displays the below message.

Users with the Modify Locked Study privilege will see the Edit button. On attempting to save changes, a confirmation popup appears: “This study is currently locked. Are you sure you want to proceed with modifications?”

  • [Yes] → Changes are saved

  • [No] → Action is canceled

Modify Locked Study - UAC Privilege​

This new UAC privilege allows select users (e.g., QA, Lead Techs) to edit locked studies while maintaining the system’s integrity. These privileges are GUI-based role UAC controlled and assignable to all roles at each organization level.

UAC Permission​

  • If a user has this UAC permission ON, they can modify studies even when the study is locked due to PRIOR status.

  • If a user does not have this UAC permission (UAC OFF), they should have read-only access to locked studies (all fields of Study/Player assignment).

Behavior Based on UAC Permission​

  • UAC ON (privileged user): Can edit locked PRIOR studies, with confirmation popup.

  • UAC OFF (non-privileged user): Read-only access, no edit buttons, see tooltip on hover.
