• What is the cause and solution for SAP error message CNV_20200_CHECK159 - No duplicate asset numbers will occur for the participating company codes ?

  The SAP error message CNV_20200_CHECK159 indicates that there is an issue related to asset numbers in the context of a data migration or conversion process, particularly when using the SAP Conversion Tools (like the SAP S/4HANA Migration Cockpit). The message states that "No duplicate asset numbers will occur for the participating company codes," which suggests that the system has detected potential duplicate asset numbers across different company codes.
  Cause:
  
  Duplicate Asset Numbers: The primary cause of this error is the presence of duplicate asset numbers across the participating company codes. In SAP, asset numbers must be unique within a company code, and if the same asset number is being used in multiple company codes, it will trigger this error.
  Data Migration Issues: During data migration, if the source system has not been properly cleansed or if there are inconsistencies in the asset number assignments, this can lead to duplicates.
  Configuration Settings: The configuration settings for asset accounting may not be set up to allow for the same asset number across different company codes.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to query the asset master data tables (e.g., ANLA, ANLB) to identify any duplicate asset numbers across the company codes.
  Data Cleansing: Cleanse the data in the source system to ensure that asset numbers are unique across the participating company codes. This may involve renaming or reassigning asset numbers.
  Adjust Configuration: Review the configuration settings in the Asset Accounting module to ensure that they align with your business requirements regarding asset number uniqueness.
  Use Unique Number Ranges: If necessary, consider using different number ranges for asset numbers in different company codes to avoid conflicts.
  Testing: After making the necessary changes, perform testing to ensure that the error does not reoccur during the migration process.
