Metrics

Hi,

I built a new model using data model wizard and loaded items, locations, and sales data. Triggered the analytical engine which generated the forecast. Now when I look into mdp_matrix table I can see some metrics getting calculated (eg MAPE) .

Want to understand how can MAPE be calculated like this way without have actuals being loaded for the next planning cycle. If I am not wrong MAPE should be equal to Current Actuals-Archived forecast/ Current actuals. Without having any archived forecast version at this moment, how is demantra calculating mape and other metrics ?

Thanks
