• What is the cause and solution for SAP error message CNV_INDX109 - Conversion of nested structures (&1) not supported (Component &2) ?

  The SAP error message CNV_INDX109 indicates that there is an issue with the conversion of nested structures during a data migration or conversion process. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion programs.
  Cause:
  The error occurs when the system encounters a nested structure (a structure that contains other structures) that it does not support for conversion. This can happen due to:
  
  Complex Data Structures: The data model being migrated contains nested structures that are not compatible with the conversion logic implemented in the migration tool.
  Configuration Issues: The configuration of the migration tool may not be set up to handle certain types of nested structures.
  Data Model Changes: Changes in the data model between the source and target systems may lead to unsupported structures.
  
  Solution:
  To resolve the CNV_INDX109 error, consider the following steps:
  
  
  Review the Data Model: Check the source data model to identify the nested structures causing the issue. Understand how these structures are defined and how they relate to the target data model.
  
  
  Flatten the Structure: If possible, modify the source data to flatten the nested structures. This may involve creating additional fields or tables to hold the data in a non-nested format.
  
  
  Adjust Migration Logic: If you have access to the migration tool's configuration, you may need to adjust the logic to handle nested structures. This could involve custom coding or using specific transformation rules.
  
  
  Consult Documentation: Review the SAP documentation related to the migration tool you are using. There may be specific guidelines or limitations regarding nested structures.
  
  
  Seek SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They may provide patches, updates, or specific guidance based on your system configuration.
  
  
  Testing: After making changes, conduct thorough testing to ensure that the data migration works as expected without errors.
