APODP How Forecast model for different product can be define ?

Hi Gurus,

I had forecast 1000 products and in that thousand products i have 300 slow moving products and 700 fast moving products.

I had taken Linear regression model for this products and run the forecast. My question is i wanted to forecast 300 slow moving products with Seasonal Model , can anyone please mention how we can forecast 1000 products with two different forecast models?

Waiting for your answers

Regards & Thanks
