Projection API calls for "Requisition to Order"

Hi,

I need help with the list of API Calls to perform on the Part Requisition Lines → "Requisition to Order" → “Create New” steps using the projection API calls.

 I tried using the “PurchaseRequisitionHandling.svc/PurchaseReqLinePartSet(RequisitionNo='22585',LineNo='2',ReleaseNo='1')/IfsApp.PurchaseRequisitionHandling.PurchaseReqLinePart_RequisitionToOrder” but that didn’t create the PO but the status got updated to PO Created.

Thanks,

Sume
