Dimension Size Vs Fact Size
The current size of all dimensions can be monitored in relation to fact table by t-code se38 running report SAP_INFOCUBE_DESIGNS.Also,we can test the infocube design by RSRV tests.It gives out the dimension to fact ratio
The ratio of a dimension should be less than 10% of the fact table.In the report,Dimension table looks like /BI[C/O]/D[xxx]
Fact table looks like /BI[C/0]/[E/F][xxx]
Use T-CODE LISTSCHEMA to show the different tables associated with a cube.
We used the SAP program Sap_Infocube_designs to check the structure of the InfoCubes to ensure they had a “good” profile (a good profile means that the dimension tables were small against the fact table row).
