  The SAP error message CPWB126, which states "Switch to change status of superior object not possible," typically occurs in the context of project management or change management within SAP, particularly when dealing with project structures or change requests.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Status Restrictions: The superior object (like a project or a change request) may be in a status that does not allow changes. For example, if the superior object is locked or in a completed status, you may not be able to change its status.
  
  
  Dependencies: There may be dependencies or relationships with other objects that prevent the change. If the superior object has subordinate objects that are in a certain status, it may restrict the ability to change the status of the superior object.
  
  
  Authorization Issues: The user may not have the necessary authorizations to change the status of the superior object.
  
  
  Configuration Settings: There may be specific configuration settings in the system that restrict status changes based on certain criteria.

  To resolve the CPWB126 error, you can take the following steps:
  
  
  Check Object Status: Verify the current status of the superior object. If it is in a status that does not allow changes (like "Completed" or "Locked"), you may need to change it to a status that permits modifications.
