  The SAP error message RS2HANA_AUTH187 indicates that there is an issue with the database user mapping in the context of SAP HANA. Specifically, it means that the database user (DBMS user) associated with a particular SAP user does not exist in the HANA database. This can occur in scenarios where SAP is trying to authenticate or authorize a user for accessing HANA database resources.
  Cause
  The error can be caused by several factors:
  
  User Mapping Issues: The SAP user is not correctly mapped to a corresponding database user in HANA.
  Database User Does Not Exist: The specified database user has not been created in the HANA database.
  Incorrect Configuration: There may be misconfigurations in the SAP system regarding the database connection or user authorizations.
  User Deletion: The database user may have been deleted or renamed after the mapping was established.
  
  Solution
  To resolve the error, you can follow these steps:
  
  
  Check User Mapping:
  
  Verify the mapping of the SAP user to the HANA database user. This can typically be done in the SAP system under the user administration settings.
  Ensure that the database user exists in the HANA database.
  
  
  
  Create the Database User:
  
  If the database user does not exist, you will need to create it in the HANA database. This can be done using SQL commands or through the HANA Studio.
  Example SQL command to create a user:
  CREATE USER <DB_USER> PASSWORD '<password>';
  
  
  
  
  Assign Roles and Privileges:
  
  After creating the user, ensure that the necessary roles and privileges are assigned to the user so that they can access the required resources.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the SAP system to ensure that the connection to the HANA database is correctly set up.
  Check the DBMS_USER and DBMS_PASSWORD settings in the relevant configuration files or transaction codes.
  
  
  
  Test the Connection:
  
  After making the necessary changes, test the connection to ensure that the user can now access the HANA database without encountering the error.
  
  
  
  Consult Documentation:
  
  If the issue persists, consult the SAP documentation or support resources for further troubleshooting steps specific to your version and configuration.
