  The SAP error message CNV_20100528 typically occurs during data migration or data upload processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the data being uploaded does not match the existing data in the target system, which can lead to inconsistencies or conflicts.
  Cause:
  The error message can be triggered by several factors, including:
  
  
  Data Mismatch: The data being uploaded (e.g., master data, transactional data) differs from the data already present in the target system. This could be due to:
  
  Different values for the same key fields.
  Changes in the data structure or format.
  Data that has been modified in the target system after the extraction.
  
  
  
  Data Integrity Violations: The uploaded data may violate business rules or constraints defined in the target system, such as unique constraints or foreign key relationships.
  
  
  Incorrect Mapping: The mapping of fields between the source and target systems may not be correctly defined, leading to discrepancies.
  
  
  Data Type Issues: There may be differences in data types or lengths between the source and target systems.
  
  
  Solution:
  To resolve the CNV_20100528 error, consider the following steps:
  
  
  Review the Data: Check the data being uploaded against the existing data in the target system. Identify the specific records that are causing the mismatch.
  
  
  Data Validation: Ensure that the data being uploaded adheres to the business rules and constraints of the target system. Validate the data for integrity and consistency.
  
  
  Adjust Mapping: If the error is due to incorrect mapping, review and adjust the mapping configuration in the migration tool to ensure that fields are correctly aligned.
  
  
  Data Cleansing: Cleanse the data in the source system to ensure it matches the expected format and values in the target system. This may involve correcting data types, lengths, or values.
  
  
  Conflict Resolution: If there are conflicts with existing data, decide whether to update the existing records, skip them, or handle them in another way based on business requirements.
  
  
  Testing: After making adjustments, perform a test upload with a smaller dataset to verify that the issue has been resolved before proceeding with the full upload.
