In order to see all Purchase Orders in ApprovalMax, the user must be the Requester of all Purchase Orders, or assigned to the Administrator role.
Purchase Order Requesters, Approvers or Organisation Administrators can use the GRN functionality to reflect the delivery status and attach the delivery note to an approved Purchase Order.
Or, as a workaround, such users can upload delivery notes to approved Purchase Orders in ApprovalMax - but only in the Purchase Order's comments section.
No attachments, whether they are in the GRN or comment section, will be synced to Xero.
If you need to reflect delivery notes in Xero, they should be uploaded in Xero to the respective Purchase Order, which must then be updated in Xero and manually synced to ApprovalMax by refreshing the requests list. With this done, the delivery notes will appear as an attachment to the Purchase Order in ApprovalMax.
