The original name from the data source for a renamed field is always displayed in the title of the [Rename Field] dialog to make identifying its origin easier. The [Reset] button allows you to swap it back to its original name for Dimensions and Measures. Calculated Fields and Parameters can be renamed, but there is no ability reset them to their original name once they are changed.

|---|
Be aware that renaming a Dimension, Measure or Parameter can cause a Calculated Field to become invalid if it expects to use a particular field name that no longer exists in its calculations. You will get a warning if your field is in use within a Calculated Field before you rename it. |
