  Cause:
  
  
  Blocked Activity Type: The most common cause of this error is that the activity type in question has been marked as blocked in the system. This can happen due to various reasons, such as:
  
  The activity type is not intended for use in the current period.
  The activity type has been deactivated or blocked by a user or during a configuration change.
  The activity type is not assigned to the relevant cost center or internal order.
  
  
  
  Configuration Issues: There may be configuration settings in the controlling area or the activity type that prevent its use.
