Using conditional formatting, you can format selected characteristics (such as customer XY) differently. In the executed report, these characteristic values have the formatting you specify and are set apart from the other characteristic values in your group level.
You can apply conditional formatting only to characteristic values in dynamic sections of a data provider. A data provider with a dynamic section is based on a query (or query view) with one or more characteristics in the drilldown.
