 Custom notifications are sent to desktop or mobile for anything that needs an user's attention. To get started we need to create a Custom Notification Type by navigating to Setup | Notification Builder | Custom Notifications | New .

How to update related contacts when shared activities are logged using flow?

This feature can be turned on by navigating to Setup | Feature Settings | Sales | Activity Settings. Turning on this feature may take up to 48 hours depending on the number of tasks that already exist in the Org. Problem: Standard LastActivityDate field in contact object does not get updated on all contacts when a task is associated to multiple contacts. Only the primary contact's LastActivityDate is updated by default. Reports using LastActivityDate will have wrong Activity Date. Solution: Create a custom datetime field and update the field using the flow to track contact activities. LastActivityDate is a read only field and cannot be updated.  Expanded view of flow components for reference: Record-Triggered Flow  Get Related Task Who Records  Iterate Task Who Collection Check if the Who type is 'Contact' Bulkify the Contact Update Collection by creat
