Tableau Prep Builder 2020.1 was recently released, and it now supports Fixed Level of Detail (Fixed LOD) calculations, similar to Tableau Desktop. That means that you can use them to change the granularity of fields in your data, or create new fields using the existing data in your dataset.
The difference between fixed and include is, fixed uses the dimensions in the calculation only, while include still depends on other dimensions in the view, so the sequrence of these two calculation has been executed is different.
Granularity refers to the level of detail of the data stored in a table. … or in other words. â€What does a single row in a data table represent?†Tableau Tip: The term 'Level of Detail' (which you may have come across in many Tableau Blogs, Articles…
FIXED expressions do not explicitly ignore filters.

Answer
- Open the workbook and connect to the data source.
- Create an extract of the data source. For more information, see Extracting Data.
- Connect to the Tableau Data Extract file.
- Replace the database by Extract (the new data source).
- Close the connection to the database.
- Save the workbook as a packaged workbook (.
Level of Detail expressions (also known as LOD expressions) allow you to compute values at the data source level and the visualization level. However, LOD expressions give you even more control on the level of granularity you want to compute.
FIXED level of detail expressions compute a value using the specified dimensions, without reference to the dimensions in the view. The following examples can be recreated using the Sample - Superstore data source.
There are six different types of filters in tableau desktop based on their various objectives and are mentioned below as per their execution steps.
Applies to: Tableau Desktop, Tableau Online, Tableau Server. Data blending is a method for combining data from multiple sources. Data blending brings in additional information from a secondary data source and displays it with data from the primary data source directly in the view.

Question: When can you edit an existing filter? on Tableau Select an answer: You can edit when it is a condition filter. You can edit when the filter is not matching anything. You cannot edit a filter after adding it.
INCLUDE level of detail expressions can be useful when you want to calculate at a fine level of detail in the database and then re-aggregate and show at a coarser level of detail in your view. Fields based on INCLUDE level of detail expressions will change as you add or remove dimensions from the view.
When Aggregate Measures is selected, Tableau will attempt to aggregate measures in the view by default. This means that it collects individual row values from your data source into a single value (which becomes a single mark) adjusted to the level of detail in your view.
