Hi Chamath
Very sorry I confused you with my response. Let me clarify here:
Contractor POs are raised without a project connection, under the main hiring company. Later when they register hours against the relevant project activities, the projects are charged through multi-company project transactions. Still the POs have the auhorization setup departmentwise [also we can add a authorization group project managers if you like] Hiring contractors are seen as a department overhead at this time, later to be settled through the group company under which the project is being carried out]
The earlier mentioned authorization levels are for project purchases [non contactors] occurring through project demand > Purchase Requisition [without a value] > PO [with the value, hence with authorization levels]
Thanks,
Asela
