• What is the cause and solution for SAP error message RS2HANA_AUTH251 - SQL privilege EXECUTE on procedure &1 is already assigned to user &2 ?

  The SAP error message RS2HANA_AUTH251 indicates that there is an issue with SQL privileges related to the execution of a specific procedure in SAP HANA. The message states that the privilege to execute the specified procedure is already assigned to the user mentioned in the error message. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Privilege Assignment: The error occurs when there is an attempt to assign the EXECUTE privilege on a procedure to a user who already has that privilege. This can happen during role assignments or when executing certain transactions that require privilege checks.
  Role Management: The user may already be part of a role that has the necessary privileges, leading to redundancy in privilege assignment.
  Database Schema Issues: There may be issues related to the database schema or the way privileges are managed in the HANA database.
  
  Solution
  
  
  Check Existing Privileges:
  
  Use the SQL command to check the existing privileges for the user on the specified procedure. You can run a query like:
  SELECT * FROM "SYS"."GRANTED_PRIVILEGES" WHERE "GRANTEE" = '<user_name>' AND "OBJECT_NAME" = '<procedure_name>';
  
  Replace <user_name> and <procedure_name> with the actual user and procedure names.
  
  
  
  Role Assignment Review:
  
  Review the roles assigned to the user to see if the EXECUTE privilege is already included in any of the roles. You can check the roles using:
  SELECT * FROM "SYS"."ROLE_GRANTEES" WHERE "GRANTEE" = '<user_name>';
  
  
  
  
  Remove Redundant Assignment:
  
  If the privilege is already assigned, you can skip the assignment process or remove the redundant assignment from your role or user management process.
  
  
  
  Revoke and Reassign:
  
  If necessary, you can revoke the privilege and then reassign it to ensure that the privilege is correctly applied:
  REVOKE EXECUTE ON "<procedure_name>" FROM "<user_name>";
  GRANT EXECUTE ON "<procedure_name>" TO "<user_name>";
  
  
  
  
  Check for Errors in Role Management:
  
  Ensure that there are no errors in the role management process that might be causing this redundancy. Review the role definitions and assignments.
