  Error Message
  WS664: Mandatory roles cannot be deleted
  
  Cause
  This error occurs when you attempt to delete a mandatory role in SAP. Mandatory roles are system-defined roles that are essential for the functioning of the SAP system or for specific users. These roles are protected by the system to prevent accidental deletion because their removal could lead to system inconsistencies or loss of critical authorizations.
  Mandatory roles typically include:
  
  Standard SAP roles required for basic system operations.
  Roles assigned by the system to users that cannot be removed due to system integrity.
  Roles that are part of composite roles or assigned via user master records with mandatory flags.
  
  
  Solution
  
  Do not delete mandatory roles: Since these roles are essential, the recommended approach is to not delete them.
  Check role assignment: If you want to remove a role from a user, try removing the role assignment from the user rather than deleting the role itself.
  Use custom roles: If you need to restrict or customize authorizations, create custom roles based on standard roles and assign those to users instead of modifying or deleting mandatory roles.
  Check role dependencies: Use transaction codes like PFCG (Role Maintenance) to analyze role dependencies and assignments.
  Consult SAP documentation or Basis team: If you believe a mandatory role is no longer needed, consult with your SAP Basis or Security team before taking any action.

  Role Types:

  Best Practices:
  
  Always back up roles before making changes.
  Use transport requests to move roles between systems.
