• What is the cause and solution for SAP error message /IAM/OBJECT_INT129 - Extraction filter &1, &2: No corresponding back-end field; aborting ?

  The SAP error message /IAM/OBJECT_INT129 Extraction filter &1, &2: No corresponding back-end field; aborting typically occurs in the context of data extraction processes, particularly when using SAP's Information Lifecycle Management (ILM) or similar data extraction frameworks. This error indicates that the extraction filter specified does not correspond to any field in the back-end system, leading to the extraction process being aborted.
  Cause:
  
  Invalid Field Reference: The extraction filter references a field that does not exist in the back-end data source. This could be due to a typo, a field that has been removed, or a field that is not available in the current context.
  Configuration Issues: The extraction configuration may not be set up correctly, leading to mismatches between the extraction filters and the available fields in the back-end.
  Data Model Changes: Changes in the underlying data model (e.g., changes in database tables or structures) may have rendered the extraction filters obsolete.
  Transport Issues: If the extraction configuration was transported from one system to another, there may be inconsistencies in the field definitions between the systems.
  
  Solution:
  
  Verify Field Existence: Check the back-end system to ensure that the fields referenced in the extraction filter actually exist. You can do this by examining the relevant database tables or data models.
  Correct the Extraction Filter: If the field does not exist, update the extraction filter to reference a valid field. This may involve modifying the extraction configuration in the relevant transaction (e.g., RSA2 for DataSources).
  Review Configuration: Ensure that the extraction configuration is correctly set up and that all necessary fields are included. This may involve checking the settings in the DataSource or InfoProvider.
  Check for Changes: If there have been recent changes to the data model, ensure that the extraction filters are updated accordingly to reflect these changes.
  Transport Consistency: If the issue arose after a transport, verify that all necessary objects and configurations were transported correctly and that there are no discrepancies between the source and target systems.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like RSA1 (Data Warehousing Workbench), RSA2 (DataSource Maintenance), or SE11 (Data Dictionary) to investigate and modify the relevant configurations.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific DataSource or extraction process you are working with.
  Documentation: Refer to SAP documentation for guidance on configuring extraction filters and understanding the data model in your specific SAP environment.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
