You need VLF EPC141006 (or later) to use this feature.
The #avFrameworkManager.avChangeCommandState method allows programmatic changing of a command's enablement state.
The associated event, avCommandStateChanged is signaled when the avChangeCommandState method successfully alters the enablement state of a command.
Refer to the shipped advanced example Command Enablement for more information.
Note: The changing of business object instance level command states within business objects that support multiple concurrently open instances is not viable because you cannot identify which open instance the state change applies to.
Note: Do not use avChangeCommandState in business objects that use Subtypes. The subtype enablement/disablement will override any enablement/disablement done by avChangeCommandState.
