Also useful to know would be these things:
1) Are you using OLAP cubes within the context of the BI Platform (also known as the SAS Platform for Business Analytics)???
2) Are you using a DI Studio job to build your OLAP cube?
3) Are you using code generated in OLAP Cube Studio to build your cube?
4) If you are using the BI Platform, do you have access to view the metadata definitions via SAS Management Console????
5) If you are not directly using the SAS BI Platform or DI Studio and/or OLAP cube studio, are you perhaps using a product called Futrix and using OLAP cubes under that context????
Finally, this is probably not the best forum to post OLAP questions. You may find some OLAP cube users/builders here, but most OLAP cubes these days are used/built/maintained under the context of the BI Platform and most of those folks can be found in the Web Report Studio forum.
As for Googling to find out more information, the documentation for PROC OLAP is here (with examples):
