Each fact table column can have a transformation associated with it. The transformation is included in the generated procedure and executed as part of the procedure update. The transformation must therefore be a valid SQL construct that can be included in a SELECT statement.
For example, we could have a transformation of 'load_order_line.quantity * 0.125' to calculate a tax column of 12.5%. Click the Transformation tab to enter a transformation.
- Transformations are only put into effect when the procedure is re-generated.
- Microsoft Analysis Services 2005+ Tabular Mode Tables: For Tabular Mode table column transformations, Default DAX is the only applicable Function Set for after load transformations.
Refer to Transformations for details.
