How does a FIXED LOD expression work with date dimensions?

A FIXED LOD expression calculates a value at the exact date level you specify, ignoring filters on that dimension but not all filters or view level changes.

beginner

Example: What does this LOD expression do? { FIXED [Order Date] : SUM([Sales]) }

It calculates total sales for each unique order date, regardless of other dimensions in the view.

Why use LOD with date dimensions instead of just using date in the view?

LOD lets you fix calculations at a specific date level even if you change the view to months or years, ensuring consistent results.

What is the difference between INCLUDE and EXCLUDE LOD with dates?

INCLUDE adds a finer date level to the calculation, while EXCLUDE removes a date level from the calculation granularity.

What does { FIXED [Order Date] : SUM([Sales]) } do in Tableau?

A Calculates average sales per customer

B Calculates sales for each order date ignoring other dimensions

C Filters sales by the current view's date level

D Calculates total sales for the entire dataset

The FIXED LOD fixes the calculation at the Order Date level, ignoring other dimensions.

Which LOD expression would you use to add a finer date level to your calculation?

A INCLUDE

C EXCLUDE

D FILTER

INCLUDE adds a finer level of detail, such as a more granular date level.

If you want to ignore filters on date in your calculation, which LOD keyword helps you?

A FIXED

B INCLUDE

C EXCLUDE

D AGGREGATE

FIXED LOD expressions ignore filters on the specified dimension.

What happens if you use EXCLUDE [Order Date] in an LOD expression?

A It filters data by Order Date

B It adds Order Date to the calculation granularity

C It fixes the calculation at Order Date level

D It removes the Order Date level from the calculation granularity

EXCLUDE removes the specified dimension from the calculation level.

Why is LOD useful with date dimensions in Tableau?

A To change date formats

B To sort dates alphabetically

C To create calculations independent of the view's date level
