This function is only available if you have chosen a hierarchy for at least one characteristic. You can choose a hierarchy using the function Extras ® Choose hierarchy in the report definition or Edit ® Hierarchy ® Choose from the report list.
The function Set focus lets you display a particular branch of your report by itself in order to analyze it more closely. The rest of the report is not displayed.
To reverse this function and display the entire hierarchy again, choose the function Undo focus either from the menu or directly from the report list.
