Hi Velmurugan,
In Table MAPR you will not see any forecast value. Table MAPR gives the Pointer (PNUM1) and then with this Pointer you should access table PROP to see the forecasting parameters.
Forecasting values can be seen in MVER. Check this thread to understand the logic behind MVER:
Explain Table MVER (Materail Consumption)
Kind Regards,
