  The SAP error message DDU012 indicates that there is an issue with an inactive nametab for an ABAP Dictionary object. This typically occurs when the system is trying to access a dictionary object (like a table, view, or data element) that is not active or has an unexpected object type.
  Cause:
  
  Inactive Object: The ABAP Dictionary object (like a table or structure) is not activated. This can happen if the object was created or modified but not activated.
  Object Type Mismatch: The system is expecting a certain type of object (e.g., a table) but finds a different type (e.g., a view or data element).
  Transport Issues: If the object was transported from one system to another, it might not have been activated in the target system.
  Corrupted Object: There might be corruption in the object definition or its dependencies.
  
  Solution:
  
  
  Activate the Object: 
  
  Go to the ABAP Dictionary (transaction SE11).
  Find the object that is causing the issue (the name will be indicated in the error message).
  Check if it is inactive. If it is, activate it by clicking on the "Activate" button.
  
  
  
  Check Object Type:
  
  Ensure that the object type matches what is expected. If the system is looking for a table, ensure that the object is indeed a table and not a different type.
  
  
  
  Transport Management:
  
  If the object was transported, ensure that all related objects were also transported and activated in the target system.
  
  
  
  Check Dependencies:
