As in BEx Analyzer, there is important information that you would like to represent in a Workbook. If you have worked with BEx Analyzer, this screenshot should be familiar.
In Analysis Office you can now insert this information easily via the Ribbon Menu.
If the standard information is not enough, you can use the formula =SAPGetInfoLabel to add additional fields to your workbook. It is interesting in the context of Multiproviders. More information how to use the formula, can you find in the SAP UserGuide.
