• What is the cause and solution for SAP error message CNV10400035 - Characteristic: &1 is assigned in more than one table ?

  The SAP error message CNV10400035 indicates that a characteristic (in this case, represented by &1) is assigned to more than one table in the context of a data migration or conversion process. This typically occurs during the use of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  The error arises when the system detects that a characteristic is being referenced in multiple tables, which can lead to ambiguity or conflicts during data processing. This situation can occur due to:
  
  Data Model Conflicts: The characteristic may be defined in multiple contexts or tables, leading to confusion about which table should be used for data extraction or transformation.
  Incorrect Configuration: There may be an issue with the configuration of the data migration project, where the same characteristic is mistakenly assigned to multiple tables.
  Legacy Data Issues: If you are migrating data from a legacy system, the data model in the legacy system may have characteristics that are not properly aligned with the target SAP system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Characteristic: Determine which characteristic is causing the issue by checking the error message details. The &1 placeholder will be replaced with the actual characteristic name in the error message.
  
  
  Review Table Assignments: Check the configuration of the data migration project to see where the characteristic is assigned. You can do this by reviewing the mapping and transformation rules in the migration tool.
  
  
  Consolidate Assignments: If the characteristic is indeed required in multiple tables, consider whether it can be consolidated into a single table or if it needs to be split into different characteristics for clarity.
  
  
  Adjust Data Model: If necessary, adjust the data model in the source or target system to ensure that the characteristic is only assigned to one table or is appropriately defined in a way that avoids conflicts.
  
  
  Test Migration: After making the necessary adjustments, run a test migration to ensure that the error is resolved and that the data is being processed correctly.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the migration tool you are using, as there may be additional considerations or best practices.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
