The headings in our view were generated by the Auto-classifier, so how can we modify them?
To do this we use the Classifier. Click the Classifier button to produce the dialog shown below.
From here we can Insert and Delete items.
It can be used to specify Alias names.
Although the tree acts as a filter by including or excluding branches from the output, it is sometimes more convenient to use the filter facility in the Classifier. Double-click the filter column at Pos 4 to produce the dialog shown below.
Change the values and filter type then click OK. Click OK again in the main Classifier dialog to see the effect of the filter change.
Non-aggregate fields are pre-filtered, i.e. before inclusion into the tree.
Aggregate results are post-filtered, i.e. after being evaluated.
