In Salesforce, to ensure that specific Knowledge articles are submitted for approval automatically, you can leverage an autolaunched Flow. This approach removes the dependency on agents to manually click the 'Submit for Approval' button, thereby reducing the risk of articles bypassing the necessary approval process.

Implementation Steps:

Approval Process Configuration:First, set up an Approval Process for the Knowledge object, defining the entry criteria based on article types and categories that require approval.

Autolaunched Flow Creation:Create an autolaunched Flow that is triggered when a Knowledge article meets the specified criteria. Within this Flow, use the 'Submit for Approval' core action to programmatically submit the article into the Approval Process.

Triggering Mechanism:Implement a record-triggered Flow that invokes the autolaunched Flow upon creation or update of a Knowledge article that matches the approval criteria.

By automating the submission process, you ensure that all relevant articles undergo the necessary approval steps without relying on manual intervention. This method aligns with Salesforce best practices for automating approval processes using Flow.
