i have a new product called "Mickey". For this I have in the lifecycle tile create an entry with a referenzproduct and a function for der start and end periode.
The refernce prodcut has values in the DELIVEREDQTY and in the ACTUALQTY.
If I now start a forecast modell (this considered lifescycle) than the result of the calculation is for the forecast error (MAPE) always 0 . For that reason, I have no statistical forecast.
Can you explain me, why the result is 0 ?
Thanks in advance
