Types of LOD expressions There are three types of LOD expressions you can create in Tableau: FIXED INCLUDE EXCLUDE You can also scope an LOD expression to the table. This is called a Table-Scoped LOD expression. FIXED FIXED level of detail expressions compute a value using the specified dimensions, without reference to the dimensions in the view. Example The following FIXED level of detail expression computes the sum of sales per region: {FIXED [Region] : SUM([Sales])} This level of detail expression, named [ Sales by Region ], is then placed on Text to show total sales per region. The view level of detail is [ Region ] plus [ State ], but because FIXED level of detail expressions do not consider the view level of detail, the calculation only uses the dimension referenced in the calculation, which in this case is Region. Because of this, you can see that the values for the individual states in each region are identical. For more information ab...
