PO Cancel & Close using VB Excel Add-In

We are trying to test PO Cancel and PO Close both at header and line level using VB excel Add-in.

RESTAPI used is ⇒ /fscmRestApi/resources/11.13.18.05/draftPurchaseOrders/describe

When we use the above API and update, its getting into error as 'Attribute set for Status Code in entity Draft PO failed'.

Pl let us know if we can use this API for update or should we use a different API for CANCEL and CLOSE PO HEADERS and LINES.
