In this lesson, I share the Generate Orders Package Implementation Guide with you. In that guide you can refer to each step of the various flows found in the package, along with a description of each.
We then cover how to launch a flow from a Custom Button.
Two of the three custom buttons work, but the third does not. Your module assignment will be to troubleshoot what went wrong with the third custom button that threw an error.
