Time Series Macro Issue

[Billigans]

Hello All, 

I get the following errors when I run a time series batch macro for ARIMA modeling with a covariate. The macro is running each SKU in batches. The error does not appear when I run the same record set in the actual macro, only when I run it in the wrapper. Any help is greatly appreciated.

Hi there

One of your issues were the NULLs present in Sum_Rev and Item#.

I have created a sample workflow as attached with the TS Model Factory tool.  I think it is a better one for you to understand what is happening.

Ultimately you do not have enough data for each item# group to produce a time series or to create a forecast.
