Having this discussion about member names in mind (http://support.sas.com/forums/thread.jspa?messageID=48632뷸)
what are the rules for those? I did not find anything in the OLAP documentation.
1. Can members have the same name within a hierarchie (probably not).
2. can members have the same name within a dimension - two members on multiple hierarchies with the same name?
3. Can members have the same name when in completely different dimensions? - probably yes.
Since there is no such concept as "shared members"* in SAS OLAP we would make sure
that each member is unique within ?1-3? to make it a unique member, right?
