# Using extension point for planned work management

# Using extension point for planned work management {#ariaid-title1}

Release version: Yokohama

Extension points enable you to extend the functionality of an application and integrate
customizations without altering the application code. Extension points are stored in the
Extension Point \[sys_extension_point\] table.
The Planned Work Management plugin (com.snc.fsm_planned_work_management) adds the
global.PlannedMaintenanceExtensionPoint extension point, which creates
a logic to create work orders for the planned work schedule using the enhanced capabilities
of Planned work management.  
The default extension points that are provided with an application cannot be modified or deactivated. If modification is necessary, if you have the administrator role, you can do the following:

* Create an implementation of an extension point.
* Make any necessary changes in the implementation.
* Update the order of the implementation to a lower number. The system executes the implementation with the lowest order number.  
  Note:  
  API names used in the implementation must remain the same so the extension point can identify the implementation. Otherwise, an error results.
