LinkedTxn	array	Optional	Zero or more transactions linked to this object. The LinkedTxn.TxnType can be set to PurchaseOrder or it can also be set to ReimburseCharge . Use LinkedTxn.TxnId as the ID of the transaction. When updating an existing Bill to link to a PurchaseOrder a new Line must be created. This behavior matches the QuickBooks UI as it does not allow the linking of an existing line, but rather a new line must be added to link the PurchaseOrder. Over the API this is achieved by simply updating the Bill Line.Id to something new. This will ensure old bill line is deleted and the new line is linked to the PurchaseOrder. Be aware that for this PurchaseOrder-Bill linking to work all LinkedTxn child attributes are required. See child attributes below.
