Explanation

When a user is assigned to an account with a role that does not have the "View Devices" permission and when the System configuration option "Enforce device management permissions across accounts" is enabled in the FNO for "End-User Portal Setup", and the user accesses the device in the end user portal, this error message is displayed.

Use Case 1: [Accessing the device in the End User portal for two different accounts linked to the same user when the system configuration is enabled]

1. Customer User details.

2. In the FNO -> System Configuration -> End-User Portal Setup -> Select the checkbox for this option "Enforce device management permissions across accounts". This controls the capabilities available on the Device Details page. When a user with multiple accounts select a device, their permissions to view or manage devices, will be applied based on the ownership of the device within that selected account.

3. Then, in the end user portal device page, the user can access 'TestSA01' device without any issues. But, when the same user tries to click on 'TestSA02' device which is linked to 'TestAc-4' account id, encounters an error message- "Insufficient permissions to view the device within the account."

Use Case 2: [Accessing the device in the End User portal for two different accounts linked to the same user when the system configuration is disabled]

1. When the system configuration "Enforce device management permissions across accounts" is disabled, then the same user with the account 'TestAc-4' can access the 2nd device 'TestSA02' without any issues.
