• What is the cause and solution for SAP error message DB_SCHEMA_MAP102 - &1 already exists as schema with automatic mapping ?

  The SAP error message DB_SCHEMA_MAP102 indicates that there is an issue with schema mapping in the database. Specifically, it means that a schema with the name specified in the error message already exists and is set up for automatic mapping. This can occur during database operations, such as when trying to create a new schema or when performing a database migration or upgrade.
  Cause:
  
  Existing Schema: The schema you are trying to create or map already exists in the database.
  Automatic Mapping Conflict: The existing schema is already configured for automatic mapping, which can lead to conflicts when trying to create or modify schemas.
  Database Configuration Issues: There may be inconsistencies in the database configuration or schema definitions.
  
  Solution:
  
  Check Existing Schemas: Verify the existing schemas in your database. You can do this by querying the database directly to see if the schema already exists.
  SELECT * FROM information_schema.schemata WHERE schema_name = 'your_schema_name';
  
  Modify or Drop Existing Schema: If the existing schema is not needed, you can drop it using:
  DROP SCHEMA your_schema_name CASCADE;
  Be cautious with this operation, as it will remove all objects within that schema.
  
  Rename the New Schema: If you need to keep the existing schema, consider renaming the new schema you are trying to create to avoid the conflict.
  Review Automatic Mapping Settings: Check the settings for automatic mapping in your SAP system. You may need to adjust these settings to resolve the conflict.
