Since last week SAP published the latest version of Analysis Office 2.7 SP5. I don't know if any other version ever had a service pack so high like the actual version. At this time SAP doesn't offer the newst help file under help.sap.com/boaa. So stay tuned if there is something happening. Here is an overview about what they fixed:
In my current project we have the hide a position in a hierarchy, because it is a departmental requirement. The hierarchy is used by many departments so we cannot change it and we also don't want to have the same hierarchy two times (except for the one position). So we first excluded the position in the query.
