You've clarified with your manager the results needed from the business case. To begin with, they need visualizations showing the amounts and invoice counts for total spending and VAT related transactions by month. The best approach is aggregation by grouping.

For this exercise, you'll group and aggregate the relevant data and adjust the names to make it easier to work with.

If you lost any progress, browse your Local space, click on the case Study - financial analysis in KNIME folder, and load the 3_2_merging workflow from the Exercises folder.
