Hi when an Item is in approval flow, you cant see the item under the supplier if you call the supplier and look for all the items for that supplier. It does not appear in the inbox for supplier. It is really misleading. Please leave the items under inbox until and it gets published or create an 'Under Approval' section within supplier and park the invoices there which are waiting for approval. Currently the invoice vanishes from supplier view when it moves from inbox to waiting for approval stage.
