[SalesForce] Track Actual Approver of Approval Process – Process Builder /Flow

This is all definitely possible inside Salesforce's approval process. It utilizes approval steps. This would utilize a 3 step approach.

Here is a Youtube demonstration of a scenario of requiring two approvers. Here is another Youtube video from a Dreamforce session that goes more into depth on workflow and approval process.

Finally, here are some more examples of approval process to help you along.

What you could do is create a checkbox field on the object you're working with, which would serve as a flag to prevent recursion and the approval process from firing again. You should be able to do something like this:

• Create a new checkbox field (let's call it Approval Flag)
• In the approval process, add a step upon submission to check the Approval Flag field to TRUE
• Update your process builder criteria to look at the Approval Flag field. Add the logic of Approval Flag = FALSE in addition to your other logic to kick off the flow.

This should help prevent the misfiring.
