The status of the CRO is at ‘Released’ and the status of the repair line is at ‘completed’.

The status of the Exchange line is at ‘in exchange’ and this needs to brought to ‘completed’ to close the CRO from the header level. 

A customer order is created to the exchange part and the customer order is at ‘invoiced/ closed’ status. 

Can anyone help me with the procedure to complete the exchange line by sending out the exchange part to the customer and not received back.
