With Lumira Designer 2.1 SP01, SAP has enhanced rendering of the CROSSTAB with a clipboard function.
This clipboard function unfortunately is not compatible with older biExport versions. You will receive an error or blank pages when you try to export a CROSSTAB.
If you plan to migrate to Lumira Designer 2.1 SP01 or higher, make sure to install biExport version 2.6 or higher!
