The workflow creator can end a workflow process at a specific Step by clicking on the "End process at this approval step" button:
Example: Let's say your approval process only needs 1 reviewer to validate purchases under $50 and 2 reviewers for purchases over $50.
Define Step 1
Step 1 will have a conditional approval for Reviewer to process all requests greater than 50
The default Reviewer will process all requests under 50. Click on "End the process at this approval step" to end the process.
Define Step 2
The default Reviewer in Step 2 will process all requests as only amounts greater than 50 will go to this Step
Repeat for Step 3, if required
Tip: Only collect numbers on your Google Form. If the requester enters a currency symbol the conditional approval will not be met and the request will be sent to the default reviewer.
For example, set a Response validation on your Google Form so that requesters get an error text when they enter $ sign
