• What is the cause and solution for SAP error message CNV_10501109 - OBJNR tables could not be excluded from the conversion ?

  The SAP error message CNV_10501109 indicates that certain tables identified by the object number (OBJNR) could not be excluded from a data conversion process. This error typically arises during data migration or conversion activities, particularly when using SAP's Conversion Tools or during system upgrades.
  Cause:
  
  
  Data Dependencies: The tables in question may have dependencies on other tables or data that are required for the conversion process. If these dependencies are not resolved, the system will not allow the exclusion of these tables.
  
  
  Configuration Issues: There may be configuration settings in the conversion tool that are not set correctly, leading to the inability to exclude certain tables.
  
  
  Custom Code or Enhancements: If there are custom developments or enhancements that reference the tables, the conversion process may prevent their exclusion to maintain data integrity.
  
  
  Inconsistent Data: The data within the tables may not meet the criteria for exclusion, such as having records that are still needed for the conversion.
  
  
  Solution:
  
  
  Review Dependencies: Check the dependencies of the tables that are causing the error. Ensure that there are no other tables or processes that rely on the data in these tables.
  
  
  Adjust Configuration: Review the configuration settings in the conversion tool. Ensure that the settings allow for the exclusion of the specified tables.
  
  
  Analyze Custom Code: If there are custom developments, analyze the code to determine if it references the tables in question. If so, you may need to modify the code or the conversion process to accommodate the exclusion.
  
  
  Data Cleanup: If the data in the tables is inconsistent or not meeting the exclusion criteria, perform a data cleanup to ensure that the tables can be excluded.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific conversion tool you are using. There may be specific guidelines or prerequisites for excluding tables.
  
  
  Seek SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They may provide insights specific to your system configuration and the conversion process you are undertaking.
  
  
  Related Information:
