  Consult Documentation: Review SAP documentation or notes related to the specific maintenance view and the underlying table to understand the implications of any changes.
  
  
  Contact SAP Support: If you believe that the change is necessary and you have a valid reason, you may need to contact SAP support for guidance on how to proceed without violating system integrity.
