Forecasting model not available with specific attribute selection in IBP Excel add-in

[mRenk]

Hi all,

I have created a compound MDT including three custom MDTs with the following keys:

CUSTID
PRDID
ZZLAND (simple custom MDT)
ZZVBID (simple custom MDT)
ZZVGID (simple custom MDT)

This MDT is the base planning level for both Actuals Qty as well as Forecast Qty, which are used as the input and target keyfigures in the forecasting model. The model is monthly, has no preprocessing steps, several methods with "calculate best forecast model based on MAPE" and MAPE as the postprocessing.

Here is my problem. When executing the forecast either in excel or application job the forecasting model is not always available, based on the attribute selection. When selecting Month and only attribute PRDID I see the model, when I add ZZVBID to the attribute selection the model is not available.

What I have found out so far is, if I reduce the forecasting steps to a single method it works. Also the setting with weighted average for multiple forecasting methods does not work. Assigning the combinations in the forecast model assignment app is possible, but the checkmark in the execution is greyed out.

Thanks a lot for your ideas!

Regards,
Maike
