Since every lab is a little different, there are two options for the number of steps in the Requests workflow:
No approval step (requester --> purchaser): The person who is approving a request is also the person who is in-charge of purchasing. For example, the scientist makes the request with the lab manager, who directly orders the item, without seeking approval. In this case, a request goes from New to Ordered.
With approval step (requester --> approver --> purchaser): An additional person (like the PI) must approve orders before they are placed. For example, the scientist makes a request which must be approved by the PI before it can be ordered by the lab manager. In this case, a request goes from New to Approved to Ordered.
Here's how Lab Admins can edit this setting:
1. On the top left side of the toolbar, click on All Labs (or the Lab name) and then click Manage.
2. Select the Lab on the left sidebar and choose the Lab Settings tab.
3. Scroll to Do all item requests require approval before they can be ordered? and select the appropriate workflow. Click Save Changes.
