Cool, this is something I have been looking into for a dashboard I'm building. My strategy was actually to compile the forecasted data in the data load. So, I would load in all of the sales data up until the most recent data that I have available, then I would LOOP over a CONCATENATE statement to add in forecasted data based on some equation.

Does this make sense? You may need to rework that Date field you have so it's easier to use the various DATE functions in the data load. Let me know if anyone else has any good ideas for this scenario, I am very interested.

Matching linest_m and linest_b function to auto-generated trendline

Using the LINEST_B and LINEST_M functions of Qlik Sense may be another way to forecast based on trendlines. As for the 24 month average, you could do something similar with the AGGR function to calculate the average and apply it to the dates in the future.

Hi Tim,

I need to generate data for the forecast,because i need to provide that column as input column as input column for end user.

Thanks
