Why doesn't my dimensioned element include a total?
The Total Dimension value must be set at both the Dimension level and at the element level. Depending on whether you are working with Metrics or Reports generated from Datasets, the setup varies.
Please refer to this article for details: Add a "Total" or "Subtotal" to a Simple Dimension
If you are still on a Version prior to 5.2.1, you'll never see a 'total' dimension value for a Report as this feature was not supported prior to the Dataset Reporting.
