Recently installed or upgraded to BI 7.0? You will find that when using transaction ST03N to view BI Workload statistics (for OLAP,data load stats etc) that it's empty.
This is because ST03N does not read directly from the RSDDSTAT tables anymore.
Using the delivered technical content you need to load the data from RSDDSTAT into technical infoproviders which is then read by ST03N.
See SAP Note 964418 and 934848 for more information on this new feature.
