  The SAP error message RS2HANA_AUTH420 indicates that there is an issue with user authorization related to a specific schema in SAP HANA. The message typically states that the schema (denoted as &2) is already assigned to another user (denoted as &3), which can lead to conflicts when trying to assign the schema to a different user.
  Cause:
  The error occurs when:
  
  You are attempting to assign a schema to a user who already has a schema assigned to them.

  Use the Correct User:
  
  If the schema is meant to be used by a specific user, ensure that you are assigning it to the correct user and that the intended user does not already have a schema assigned.
