• What is the cause and solution for SAP error message CNV_PE314 - Data of extension table &1 could not be stored due to an error ?

  The SAP error message CNV_PE314 indicates that there was an issue with storing data in an extension table 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 scenarios.
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Integrity Issues: The data being migrated may not meet the constraints or requirements of the target extension table. This could include issues like:
  
  Missing mandatory fields.
  Data type mismatches (e.g., trying to insert a string into a numeric field).
  Violations of unique constraints or foreign key relationships.
  
  
  
  Technical Issues: There may be technical problems such as:
  
  Database locks or contention issues.
  Insufficient authorizations for the user performing the migration.
  Problems with the database connection or configuration.
  
  
  
  Configuration Errors: Incorrect configuration of the migration tool or the mapping of fields between source and target tables can lead to this error.
  
  
  Solution:
  To resolve the CNV_PE314 error, you can take the following steps:
  
  
  Check the Error Log: Review the detailed error log provided by the migration tool. This log often contains specific information about which record or field caused the error.
  
  
  Validate Data: Ensure that the data being migrated adheres to the constraints of the target extension table. This may involve:
  
  Checking for missing mandatory fields.
  Ensuring data types match.
  Verifying that there are no duplicate entries if unique constraints are in place.
  
  
  
  Review Mapping Configuration: If you are using a mapping tool, double-check the mapping configuration to ensure that all fields are correctly mapped and that there are no discrepancies.
  
  
  Check Authorizations: Ensure that the user performing the migration has the necessary authorizations to write to the target extension table.
  
  
  Database Health: Check the health of the database. Look for any locks or contention issues that might be preventing data from being written.
  
  
  Test with Sample Data: If possible, try migrating a small subset of data to see if the error persists. This can help isolate the issue.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any known issues or additional troubleshooting steps.
