In Tableau , a is a type of Level of Detail (LOD) expression that computes a value using specific dimensions, completely independent of the dimensions present in the visualization. This allows you to "set a rule in stone" for how data should be aggregated, ensuring the result remains consistent even as you add or remove fields from your chart. Syntax of a FIXED LOD Calculation
You can fix the count to the Order ID level. tableau fixed calculation
You have a dataset where one Order ID has multiple rows (different products). You want to count the distinct number of orders, but aggregation types can get tricky. In Tableau , a is a type of
→ Works even when you filter to a specific year. You have a dataset where one Order ID
| Pitfall | Why it happens | Fix | |---------|----------------|-----| | | FIXED ignores dimension filters | Move filter to Context or use INCLUDE/EXCLUDE | | Unexpected repeated values | Row-level vs aggregated calculation | Place FIXED on Detail or use as a measure | | Slow performance | Computes across entire data source | Limit dimensions, use extracts, or pre-aggregate |
Here’s a concise, example-driven review of , including its syntax, behavior, use cases, and common pitfalls.
