Hi Abir,
Purchase Order comes with MM Module in SAP. This is created to send it to the vendor whenever a Purchase has to be done.
In SAP PO is created in transaction ME21 changed in ME22 and could be Displayed in ME23.
The Table that are affected once a PO is created are EKKO (PO Header) and EKPO (PO Item).
You can alos create PO through BAPI Function Module 'BAPI_PO_CREATE' and the associated Bussiness Object is BUS2012.
Hope this would be sufficient anything else please reply.
Regards,
