If you’ve ever built a large model you’ll probably be familiar with troubleshooting a small error. In most cases these are caused by updating a formula and then not extending it to the whole calculation area (“dragging it down”). They can be tedious to spot and can take long to manifest themselves.
With Table Based Modelling (TBM), another modelling standard, calculations are made up of tables. This has many benefits. For example: calculations are done on columns, which is less prone to errors.
