• What is the cause and solution for SAP error message RS2HANA_AUTH421 - &1 on schema &2 is already assigned to role &3 ?

  The SAP error message RS2HANA_AUTH421 indicates that there is an issue with the assignment of a schema to a role in the context of SAP HANA. Specifically, the error message states that the schema you are trying to assign is already associated with a different role.
  Cause:
  The error typically occurs in the following scenarios:
  
  Schema Already Assigned: The schema you are trying to assign to a role is already assigned to another role. In SAP HANA, a schema can only be assigned to one role at a time.
  Role Management: There may be a misunderstanding or mismanagement of roles and schemas, leading to conflicts when trying to assign schemas to roles.
  
  Solution:
  To resolve the RS2HANA_AUTH421 error, you can follow these steps:
  
  
  Check Current Assignments:
  
  Use the SAP HANA Studio or SQL console to check which role the schema is currently assigned to. You can run a query to list the roles and their associated schemas.
  
  
  
  Remove Existing Assignment:
  
  If you need to assign the schema to a different role, you will first need to remove the existing assignment. This can typically be done using the SQL command:
  REVOKE <role_name> FROM SCHEMA <schema_name>;
  
  Replace <role_name> with the name of the role currently assigned to the schema and <schema_name> with the name of the schema.
  
  
  
  Reassign the Schema:
  
  After removing the existing assignment, you can then assign the schema to the desired role using:
  GRANT <role_name> TO SCHEMA <schema_name>;
  
  
  
  
  Verify Changes:
  
  After making the changes, verify that the schema is now correctly assigned to the intended role.
