• What is the cause and solution for SAP error message CNV_20200_CHECK086 - No differences in selected fields in customer master data found ?

  The SAP error message CNV_20200_CHECK086 indicates that during a data migration or conversion process, the system did not find any differences in the selected fields of the customer master data. This typically occurs in the context of data migration projects, especially when using SAP's data migration tools or during system upgrades.
  Cause:
  
  
  No Changes Detected: The primary cause of this error is that the fields being compared in the customer master data do not have any differences. This could happen if:
  
  The source and target systems have identical data for the selected fields.
  The data migration process is being executed on data that has not been modified or updated.
  
  
  
  Incorrect Field Selection: The fields selected for comparison may not be the ones that actually have differences, or the selection criteria may not be set correctly.
  
  
  Data Preparation Issues: If the data was not properly prepared or transformed before the migration, it could lead to this error.
  
  
  Solution:
  
  
  Verify Data: Check the source and target customer master data to ensure that there are indeed differences in the fields you are comparing. You can do this by running queries or reports in both systems.
  
  
  Review Field Selection: Ensure that the correct fields are selected for comparison. If necessary, adjust the selection criteria to include fields that are expected to have differences.
  
  
  Data Transformation: If the data is supposed to have differences but does not, review the data transformation process to ensure that it is correctly modifying the data as intended.
  
  
  Log Analysis: Check the logs generated during the migration process for any additional information or warnings that might indicate why no differences were found.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool or process you are using. There may be specific guidelines or known issues that can help resolve the error.
  
  
  Testing: If you are in a testing phase, consider running a test migration with a smaller dataset where you know there are differences to confirm that the migration process works as expected.
  
  
  Related Information:
  
  SAP Notes: Look for relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  Migration Tools: Familiarize yourself with the specific SAP migration tools you are using (e.g., SAP S/4HANA Migration Cockpit, LSMW, etc.) as they may have specific configurations or requirements.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
