Report Differences Between TM1 Executive Viewer and IBM Cognos Analytics with TM1 Data Sources

When using an IBM® Cognos® TM1® data source, comparable reports created in IBM Cognos Analytics and in TM1 Executive Viewer may contain different cell values. This occurs because the TM1 Executive Viewer product uses an algorithm for selecting default members for non-projected dimensions that differs slightly from traditional OLAP clients.

To avoid this problem, when filtering your reports in IBM Cognos Analytics, use context filters that match the default selections shown in the Executive Viewer user interface. This ensures that the cell values in IBM Cognos Analytics match the values in Executive Viewer.
