Maybe you are one of the lucky few who is currently working with BW on HANA and do not have to model InfoCubes anymore (from a performance perspective). But for those who still need to do this, ABAP program SAP_INFOCUBE_DESIGN could help you verify how well your InfoCubes are modelled in SAP Business Warehouse. This program collects data for every InfoCube in the BW system and counts the records available in the related dimension tables and fact table. The program then checks the ratio between the number of records in the dimension tables against the number of records in the fact table.
A ratio between 10% and 20% is considered as high cardinality and therefore indicated in red. In most cases you should avoid dimension tables larger than 10%. Of course this it all depends on how frequent the data is used in the mentioned dimension table. If possible use line item dimensions instead!
Note: The data which is used for this analysis comes from BW statistics, so be sure that if you want to analyze a specific InfoCube, statistics are created for it.
