• What is the cause and solution for SAP error message CNV_12000155 - Some unique descriptions have different values ?

  The SAP error message CNV_12000155 indicates that there are unique descriptions in your data that have different values, which can lead to inconsistencies during data migration or conversion processes. This error typically arises in the context of data transformation or migration projects, particularly when using SAP's data migration tools.
  Cause:
  
  
  Inconsistent Data: The primary cause of this error is that there are records in your source data that have the same unique identifier (like a key or ID) but different descriptions or values associated with them. This inconsistency can occur due to data entry errors, legacy system discrepancies, or issues during data extraction.
  
  
  Data Mapping Issues: If the mapping of fields from the source system to the target system is not correctly defined, it can lead to situations where the same key is mapped to different values.
  
  
  Duplicate Records: There may be duplicate records in the source data that have been incorrectly identified as unique.
  
  
  Solution:
  
  
  Data Cleansing: Review the source data for inconsistencies. Identify records with the same unique identifier and different descriptions. You may need to standardize these descriptions or decide which value to keep.
  
  
  Data Validation: Implement validation rules to ensure that unique identifiers are associated with consistent values before migration. This can involve creating reports or using data profiling tools to identify discrepancies.
  
  
  Mapping Review: Check the mapping configuration in your migration tool. Ensure that the fields are correctly mapped and that there are no conflicts in the data being migrated.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for any additional guidelines or best practices.
  
  
  Testing: After making corrections, perform a test migration to ensure that the issue has been resolved and that the data is consistent.
