How can i add information in the Information Pane of Analysis Studio to display a detailed description of a measure for end users to view. The data source for the package is a Cognos Power Cube. Can this also be done for a relational datasource?
If by a Relational Datasource you mean DMR (Dimensionally Modelled Relational) objects in Framework Manager, then you should be able to add descriptions for each measure for each language supported in your model.
To do this in Framework Manager:
Select the relevant measure from the tree pane on the left
At the top of the Properties window, click on the Language tab
