07/26/2023, 6:31 PMHi @Nasreddine D yes, that is the usual behavior of most of the intermittent methods.

07/26/2023, 6:34 PMIf you need something different to that, check the hierarchical forecast with non-intermittent methods for the upper levels. This can result in more variability (this assuming that your data has a hierarchical structure)

07/26/2023, 6:38 PMYes, this is normal and expected. Often flat lines are better than nice looking curves. The visual appeal of a generated forecast or the possibility of such a forecast to happen in general are not good criteria to judge forecasts. This is a common theme.
