Purchase Requisition created via  a Work Order. All the Lines have been released and Authorised. The Requisition was converted to a Purchase Order which has been fully managed and shows at a status of ‘closed’. The Purchase Requisition in the Work Order is still showing a status of ‘authorised’ and user is unable to change the Work Task Status’s from Work Done to Reported as is getting the following message:

Previously, once a Purchase Order was created and closed the Requisition would automatically change to a status of ‘Closed’ however this hasn’t and there appears to be no obvious solution to change to the status to closed.

Can someone advise where we are going wrong?
