Demantra Forecasts Go To Zero All Of A Sudden For A Week (Doc ID 2007480.1)

On : 7.3.1 version, Engine


We have been having this issue for a while. Forecasts for an item will stay steady, then all of a sudden go to ZEROS for all weeks. I will upload examples in this SR. Most of the times the forecast will come back the following week. We need to find the root cause of this inaccurate forecasting from Demantra.
In our Demantra Collaborator workbench our forecasts disappear(all weeks goto zero) more many items. And then comeback the following week.
We also have the reverse issue where forecasts will be steady and then double or triple for all weeks. And then go back to normal the following week.
Both of these issues have been happening for over a year. Our users do not trust the forecast generated by Demantra.
We have a consulting group in to help us and they are advising us to open an SR.

Forecasts should not drop to zero

The issue can be reproduced at will with the following steps:
1. Demantra Engine Administrator
2. Run Engine
3. View forecasts in Demantra Worksheets
