  Use Correct Function Modules: If you are using function modules to update customer data, ensure that you are using the correct ones that support the operations you intend to perform.
  Authorization Check: Verify that the user has the necessary authorizations to update customer data. If not, work with your SAP security team to grant the required permissions.
