Order of Metadata Tree Differs for TM1 Data Sources
When using a an IBM® Cognos® TM1® data source, the order of members in the
metadata tree of the Source tab of an IBM Cognos Business
Intelligence studio may differ from the order shown in TM1 Architect.
By default, TM1 Architect renders members of hierarchies using a slightly different algorithm than does IBM Cognos BI. IBM Cognos BI automatically renders member metadata from TM1 data sources in hierarchical order.
From within TM1 Architect, if you want to see how an IBM Cognos BI studio will render a hierarchy, click the Hierarchy Sort button.
