• What is the cause and solution for SAP error message RS2HANA_AUTH422 - &1 on schema &2 is already assigned to &3 ?

  The SAP error message RS2HANA_AUTH422 typically indicates an issue related to the assignment of a schema in the context of SAP HANA and its integration with SAP BW (Business Warehouse) or other SAP systems. The error message suggests that the schema you are trying to assign is already associated with another user or role, which is causing a conflict.
  Cause:
  
  Schema Already Assigned: The schema you are trying to assign to a specific user or role is already assigned to another user or role. This can happen if there are overlapping configurations or if the schema was previously assigned and not properly released.
  Authorization Issues: There may be authorization issues preventing the assignment of the schema to the desired user or role.
  Configuration Errors: There could be misconfigurations in the system that lead to this error.
  
  Solution:
  
  Check Current Assignments: Use the SAP HANA Studio or SQL commands to check which users or roles currently have access to the schema in question. You can query the system views to see the current assignments.
  SELECT * FROM _SYS_REPO.M_SCHEMAS WHERE SCHEMA_NAME = '<schema_name>';
  
  Remove Existing Assignments: If the schema is indeed assigned to another user or role and you want to reassign it, you may need to remove the existing assignment first. This can be done using the appropriate SQL commands or through the SAP HANA Studio.
  REVOKE SCHEMA <schema_name> FROM <existing_user>;
  
  Reassign the Schema: After removing the existing assignment, you can proceed to assign the schema to the desired user or role.
  GRANT SCHEMA <schema_name> TO <new_user>;
  
  Check Authorizations: Ensure that you have the necessary authorizations to make these changes. You may need to work with your SAP Basis or security team to ensure you have the right permissions.
