This activity is used to reject a selected authorization step of a purchase order. It's done from either Purchase Order/Authorization tab or Purchase Order Authorization page. The rejection follows similar rules to authorizing a step e.g. you can only reject an authorization step that you are able to authorize and you can only reject the next step if the previous has been authorized. Information about the rejection is stored on the purchase order and remains there until you release the purchase order again and retrieve new authorization steps. Information about all rejections that have been done against a purchase order is also displayed on Purchase Order page by clicking the Order History button.
