 This article introduces scalar UDF inlining, a feature under the [Intelligent query processing in SQL databases](../performance/intelligent-query-processing.md) suite of features. This feature improves the performance of queries that invoke scalar UDFs in [!INCLUDE [sssql19](../../includes/sssql19-md.md)] and later versions.
 
@@ -37,6 +37,10 @@ The goal of the scalar UDF inlining feature is to improve performance of queries
 
 With this new feature, scalar UDFs are automatically transformed into scalar expressions or scalar subqueries that are substituted in the calling query in place of the UDF operator. These expressions and subqueries are then optimized. As a result, the query plan no longer has a user-defined function operator, but its effects are observed in the plan, like views or inline table-valued functions (TVFs).
 
+### Automatic inlining of scalar UDFs in Microsoft Fabric Data Warehouse
+
+In Microsoft Fabric Data Warehouse, scalar UDFs (currently in preview) are automatically inlined at compile time when the function body and the calling query meet requirements for inlining. For more information, see [CREATE FUNCTION](../../t-sql/statements/create-function-sql-data-warehouse.md?view=fabric&preserve-view=true) and [Scalar UDF inlining](../../relational-databases/user-defined-functions/scalar-udf-inlining.md?view=fabric&preserve-view=true).

 - If a UDF references built-in functions such as `SCOPE_IDENTITY()`, `@@ROWCOUNT`, or `@@ERROR`, the value returned by the built-in function changes with inlining. This change in behavior is because inlining changes the scope of statements inside the UDF. Starting with [!INCLUDE [sql-server-2019](../../includes/sssql19-md.md)] CU2, inlining is blocked if the UDF references certain intrinsic functions (for example `@@ROWCOUNT`).
