Plan IQ historical data in data collection - should it only contain [target data]?
I'm curious about how to set the data collection - historical data.
I want to make a prediction about revenue, and have some historical data.
but I also have other historical data, which is revenue and promotion, and those data is related to the revenue data (this is known from other analysis)
but I cannot make any related data in my data collection because I cannot provide the revenue and promotion data of the future timescale (I have only past data of those)
in this case, can I put those data in the historical data (as a different line item) to make more precise forecast on revenue? Or should I limit the historical data only for the target data for prediction?
