Problem conclusion

Temporary fix

Comments

  • Problem Conclusion:
    New Tables: CP_EVENT_TYPE and CP_EVENT_DATE have been added to
    IZPCA to allow customers to tag certain dates as special to
    their circumstance,
    
    i.e. Chinese New Year, which may occur on a different calendar
     day each year.
    
    New Forecast algorithm: Fractal, and associated configuration
    is provided to allow forecasting on days identified in the above
    tables.
    
    New Event Forecast reports: Fractal forecasts have new Cognos
    reports which enables data to be filtered by Event Type.
    Existing reports CP CEC MIPS Forecast report and CP LPAR MIPS
    Forecast report will also show forecasts performed with the
    Fractal Forecast algorithm.
