An Organisation's Administrator can provide a message that will be shown to Requesters during Purchase Order creation.
This is how instructions for Purchase Order Requesters can be set up:
Find your Organisation in the main menu and open Approval workflows page under Workflows and settings section.
Click on the Purchase Order workflow.
Click on the gear icon
and scroll down.
Type in the message that will be shown to Requesters when they create a new Purchase Order.
If you don't want Requesters to see any instructions, then leave this field blank.When you finish, click on SAVE in the right upper corner of the workflow settings to save your settings.
