> ## Disabling SmartDataField (SDF) cache usage for a specified SDF

> In some cases, you know at design time that an SDF should not make use of this caching mechanism and will want to disable caching for the specified SDF.

> A SmartDataField property, `UseCache`, indicates if the specified SDF uses any cached information during execution. The default value for this property is `TRUE` for the `DynLookup` and `DynCombo` class, but you can also change this value at the class level.

> You can set this value with the Use cache toggle box in the SmartDataField Maintenance tool, available from the AppBuilder or Development tool Build menu, as shown in Figure E–1. You can set this value on the master or instance levels for dynamic viewers and only at the instance level for static viewers.
