• What is the cause and solution for SAP error message IBW019 - Notification &1 has no reference object, task list &2 will not be costed ?

  The SAP error message IBW019 indicates that a notification (in this case, &1) does not have a reference object, which is necessary for the costing process of a task list (identified as &2). This error typically arises in the context of maintenance management or production planning within SAP.
  Cause:
  
  Missing Reference Object: The notification is expected to reference a specific object (like a piece of equipment, functional location, or a work order) that is necessary for costing. If this reference is missing, the system cannot proceed with the costing of the associated task list.
  Incorrect Configuration: There may be issues with the configuration of the notification or task list that prevent the system from linking them correctly.
  Data Entry Errors: The notification may have been created without properly linking it to the required reference object due to user error during data entry.
  
  Solution:
  
  Check Notification Details: Review the notification (transaction code IW21 or IW22) to ensure that it has a valid reference object assigned. If it does not, you will need to edit the notification to add the appropriate reference object.
  Link Reference Object: If the notification is missing a reference object, you can either create a new notification with the correct reference or update the existing one to include the necessary reference.
  Review Task List: Check the task list (transaction code IA05 or IA06) to ensure it is correctly configured and linked to the appropriate notifications. Make sure that the task list is set up to reference the correct objects.
  Consult Documentation: If you are unsure about the correct reference objects or how to configure notifications and task lists, refer to SAP documentation or consult with your SAP support team for guidance.
  Testing: After making the necessary changes, test the process again to ensure that the error does not reoccur.

  User Roles and Authorizations: Ensure that the user has the necessary authorizations to create or modify notifications and task lists.
