• What is the cause and solution for SAP error message MODEL122 - All target tables already exist. Creation not necessary. ?

  The SAP error message MODEL122: All target tables already exist. Creation not necessary. typically occurs in the context of data modeling or data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA. This message indicates that the system has detected that the target tables you are trying to create already exist in the database, and therefore, it does not need to create them again.
  Cause:
  
  Existing Tables: The most straightforward cause is that the target tables have already been created in the database, either from a previous execution of the data model or from manual creation.
  Incorrect Configuration: There may be a misconfiguration in the data model or extraction process that leads the system to believe it needs to create tables that already exist.
  Development Environment: If you are working in a development environment, it is possible that previous tests or runs have already created the tables.
  
  Solution:
  
  Check Existing Tables: Verify if the target tables indeed exist in the database. You can do this by querying the database or checking through the SAP GUI.
  Drop Existing Tables: If you want to recreate the tables, you can drop the existing tables manually before running the data model or extraction process again. Be cautious with this approach, as it will delete any data currently in those tables.
  Adjust Data Model: If the tables should not be recreated, you may need to adjust your data model or extraction settings to avoid this error. Ensure that the model is configured correctly to handle existing tables.
  Use a Different Schema: If you are testing and want to avoid conflicts with existing tables, consider using a different schema or database for your testing purposes.
  Check for Errors in Previous Runs: Review logs or error messages from previous runs to ensure that there were no issues that caused the tables to be created incorrectly.
