IBP for Demand Forecast Simulation "Internal PAL error" code 73001245

[wnman2005]

Hello,

I'm trying to run the forecast simulation, and I get the following error.   Would appreciate your help in deciphering what this error means?  These KF are all at the PERPRODCUST level.

Processing planning object CUSTID = 103, PRDID = 1200

Internal PAL error; code: 73001245

Processing planning object CUSTID = 103, PRDID = 1205

Internal PAL error; code: 73001245

Here is my forecast model:

Here is my planning view

Hi,

I saw similar error IBP 5.0.  In our case, it was triple exp forecasting model, system expects 24 periods and we had 23 periods..

You may want to check historical periods

Thanks,

Hi William,

Can you share your general, preprocessing steps.

Thanks, Nikhil

Here is the preprocessing steps.  We have the historical data populated.

Looks like input parameter for either substitution or MLR is causing the PAL error.

Try to model the each algorithm as separate model to check if its due to missing or null data.

Thanks, Nikhil

I did get it to work by providing 4 historical periods of data.  What is very odd is that I defined 3 historical periods in the forecast model in the Time Settings in the General section, and it was not running, even with 3 historical periods of data defined.  I changed it to 4 and populated 4 months and it started working.

Hi William,

i believe that the Holt-Winters method requires more than 3 periods of data in order for the model to initialize (or one full season plus 3 periods for any seasonality to be detected). This explains why you dint get a forecast with only 3 periods of historical data.
