I would like to know if there is a guide/help available on how to integrate external signals, especially weather forecasts, to be used within the Gradient Boosting Demand Sensing algorithm.
I have searched the help pages / Best Practice Explorer with no success.
you can find all the information on the Demand Sensing with Gradient Boosting here: https://help.sap.com/docs/SAP_INTEGRATED_BUSINESS_PLANNING/feae3cea3cc549aaa9d9de7d363a83e6/2a35bcc6...
External signals are key figures, and they need to be at a weekly level and at the same aggregation level at which you wish to run demand sensing (e.g. if you run it at product location level, than the extra signal also needs those levels). If you want to use weather as a signal than you need to first upload the weather data as a key figure into the planning area you are using.
