Conduct procurement vs Closed project or phase

Hello Bhavana,
Hopefully the following couple of examples will assist from a 'real world' perspective:
Close Proc can include the completion and sending of acceptance certificates to specific supply chain entities. It could also include the issuing of payment(s) to same. These would typically be contract related actions/items.
Admin Closure can include the return of retention monies held. The transfer of warranty information from the project to operational units. The updating of supply chain performance aspects from an overview perspective.
