Hi Manoj,
S025 is used in REM: Repetitive Manufacturing:
Key Figures for Repetitive Manufacturing (S025/S02 - Plant Maintenance (PM) - SAP Library
The order that you have in CO03 is a production order.. this is something different. When you use REM, you don't create production orders..
As you can see in the help of S025-AUFNR, this is:
Definition: run schedule header
Production Planning and Control (PP)
The determination of a valid production version to use when producing a plant material in repetitive manufacturing and of a time period for collecting costs.
Hope this clarifies your doubt.
Kind Regards,
Mariano
