If you enable “Inventory and Sales Forecasting” in Dynamics NAV as described in the link above, then hopefully you will see similar predictions in Dynamics NAV. So continue your R project with a few more lines: TBatResult = tbats(dataset1) The good thing is that a lot of the hard work has been done for us already, and made available with a simple R command or two. That’s a model which takes seasonality better into consideration. Or why not use TBATS method (Exponential smoothing state space model with Box-Cox transformation, ARMA errors, Trend and Seasonal components). The parameters here are, apart from your dataset (selecting just column 3), the number of periods you want to forecast, confidence level.

Start R Studio or your preferred R Editor.ĭataset1 “Install packages” and type in “forecast” and install it here first.Or skip the Dynamics NAV steps and just use the dataset in the RData.csv file in the attached ZIP: SmartSolutions7 Once the codeunit has been run to insert data, use the same codeunit to dump the data to c:\Temp\RData.csv.

This data will not be business valid as it has not been posted, so don’t try to use it for any other purposes, and only run this codeunit in a demo company! It will insert a new item, LVASE “Lyngby Vase”, and some entries for it. Get some dataĪttached is a codeunit which will generate a bit of data.

And, if you prefer, use Python instead of R (but the code sample below is all R). There are many other environments you can use to run R, so pick your own favourite. In this example we use RStudio, downloaded from here. So in this post we will spend most of our time in R. The idea is to get a look at your Dynamics NAV data in a new tool that is designed for data analysis. In this post we will pull some data out of Dynamics NAV, then run R script on it to see what we get.

So there is a good potential that we can turn some of this data into Time Series to use for a machine learning algorithm for things like these: The default version of Dynamics has more than 300 tables that contain date and decimal fields, including all the history tables. In Dynamics NAV, we already use it in Inventory Forecasting as described in the blog post Smart Solutions 4. Time Series then uses this to predicting values for future periods. All you need is a dataset that contains a date and a number.

Time Series is a topic on its own in machine learning, as it is one of the cleanest examples of predicting the future.
