I have the data extracted from SAP APO using listcube function and all the data are presented horizontally.
Questions
There are multiple characteristics before a series like the product code, sub-brand, location, store etc. can i forecast without removing these characters?
Data downloaded contains more than 3000 rows and 72 columns in which 60 are 5 years of data on a monthly level. As the data are present horizontally, how can i run a forecasting model in R without changing the orientation?
Reshaping your data to a long format would make things much easier by far, and have in mind that this is not going to affect your raw data and you can easily get back to a wide format after the forecasting is done.
Thank you! Would be great if you can provide the code or what package to use to reshape the data. Also how to define the a time series starts from a particular column or row?
