• What is the cause and solution for SAP error message CODAC_ODH_MESSAGES018 - Row elimination already defined for Table &1 ?

  The SAP error message CODAC_ODH_MESSAGES018, which states "Row elimination already defined for Table &1," typically occurs in the context of data modeling or data extraction processes, particularly when working with SAP HANA or SAP BW (Business Warehouse). This error indicates that there is an attempt to define row elimination for a table that has already been configured for this purpose.
  Cause:
  The primary cause of this error is that the system has detected multiple definitions of row elimination for the same table. Row elimination is a feature used to filter out rows from a dataset based on certain conditions, and it can only be defined once for a specific table. If a user or process tries to define it again, the system will raise this error.
  Solution:

  Remove Duplicate Definitions: If you find that there are multiple row elimination definitions for the same table, you will need to remove or modify the duplicate definitions. Ensure that only one row elimination condition is applied to the table.
  
  
  Review Data Model: If you are working with a complex data model, ensure that the row elimination logic is correctly implemented and that it does not conflict with other parts of the model.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure row elimination for your specific scenario.
  
  
  Testing: After making changes, test the data extraction or modeling process again to ensure that the error is resolved.
