About Site Filtering in LOPA

Site filtering in LOPA is achieved by specifying a site on the Definition section of a LOPA and that site assignment is applied to all the related records. Users must have privileges for the relevant site to access records for the specified site. Users can be assigned to one or many sites. They will be able to see only the records that are assigned to their site(s) or those that are global records.

Site filtering is enabled for the following families:

LOPA: When you create a LOPA, you can assign it to any site. After you save the changes, you cannot modify the site for the LOPA.
Consequence Modifier: A Conditional Modifier will inherit the site from the associated LOPA.
Hazards Analysis Safeguard: A Safeguard will inherit the site from the associated LOPA.

Example

Consider an organization that has three sites, Site X, Site Y, and Site Z and contains the following records:

LOPA 1: Assigned to Site X
LOPA 2: Assigned to Site Y
LOPA 3: Assigned to Site Z

Scenario 1: User assigned to only Site X

When this user accesses the LOPA Overview page, the user will be able to see the records that are assigned to Site X:

LOPA 1: Assigned to Site X

The user will also be able to see the Consequence Modifiers and Safeguards associated with LOPA 1.

Scenario 2: User assigned to both Site X and Site Y

When this user accesses the LOPA Overview page, the user will be able to see the records that are assigned to Site X and Site Y:

LOPA 1: Assigned to Site X
LOPA 2: Assigned to Site Y

The user will also be able to see the Consequence Modifiers and Safeguards associated with LOPA 1 and LOPA 2.

Scenario 3: Super User

When this user accesses the LOPA Overview page, the user will be able to see the records that are assigned to any of the sites:

LOPA 1: Assigned to Site X
LOPA 2: Assigned to Site Y
LOPA 3: Assigned to Site Z

The user will also be able to see the Consequence Modifiers and Safeguards associated with LOPA 1, LOPA 2, and LOPA 3.
