The main SAP transaction codes (tcodes) for work orders depend on the module you're using (e.g., PM for Plant Maintenance, PP for Production Planning). Here are the most common ones:
For Plant Maintenance (PM) Work Orders:
IW31 – Create Work Order
IW32 – Change Work Order
IW33 – Display Work Order
For Production Orders (PP):
CO01 – Create Production Order
CO02 – Change Production Order
CO03 – Display Production Order
