Use Apex Managed Sharing with an after insert trigger. It allows dynamic record sharing based on user-defined criteria like the Event_Reviewer_c field.

Apex managed sharing is the correct feature to control the visibility and access to cases shared with external partners. It allows developers to programmatically create sharing records that grant access to users based on specific criteria, providing granular control over record sharing.

The issue described is likely due to the order of execution in Salesforce, where processes in Process Builder run after all before triggers. If the Opportunity's Amount is changed and the CommissionBaseAmount__c is set by Process Builder, the trigger that calculates CommissionAmount__c may not see the updated value if it operates before the process.

Replacing the process with a before-save record-triggered flow (formerly known as Fast Field Update) would ensure that CommissionBaseAmount__c is updated before the trigger runs. In a before-save flow, field updates occur before any Apex before update triggers fire, which means the trigger would have the updated value of CommissionBaseAmount__c to use in its calculation.

For mobile app pages in App Builder, best practices include limiting the number of heavy components like Tabs and Accordion because they can negatively impact performance due to increased client-side processing and data transfer. Also, using Performance Analysis in App Builder helps in identifying components that may slow down page performance and provides recommendations for improvements. References:

The loop contains a SOQL query inside, causing it to run multiple times. This will throw a QueryException because the Account query returns more than one row.

Since the SeeAllData=true annotation is used, the test class does not have its own test data and is relying on the data in the org. The org already has accounts with the name starting with "Test", so the assertion that no accounts should exist after the deletion will fail because the test method only deletes the account that was created within its scope.

Application Events in Aura components are used for communication between components that are not in the same containment hierarchy. An application event to alert users about the arrival of a guest at the front desk is appropriate because it allows any component within the app to listen and respond to the event, regardless of where it is located in the component hierarchy.

Event Monitoring Log provides the ability to track different types of events in Salesforce, including user logins. These logs can be used to determine the last login time of a user without the need for real-time notification.

The SOAP API with the Partner WSDL is ideal for building integrations that work across multiple Salesforce orgs, especially when they have varying schemas. The Partner WSDL is designed to be flexible and dynamic, catering to different metadata.
