  Cause:
  
  Namespace Restrictions: SAP systems have specific namespaces for different types of objects (like custom development objects). If a user is assigned to a namespace that is restricted or not valid, this error can occur.

  Check User Assignment:
  
  Go to transaction SU01 (User Maintenance) and check the user profile for the user in question.
  Verify the namespace assigned to the user and ensure it is valid and allowed.
  
  
  
  Remove or Change Namespace:
  
  If the user is assigned to an invalid namespace, you can either remove the user from that namespace or change it to a valid one.
