• What is the cause and solution for SAP error message CNVA_20290_CHECK079 - The participating company codes use same asset numbers ?

  The SAP error message CNVA_20290_CHECK079 indicates that there is an issue with asset numbers being duplicated across different company codes during a cross-company code transaction or integration. This typically occurs in scenarios where assets are being transferred or shared between different company codes, and the system detects that the same asset number is being used in multiple company codes, which can lead to inconsistencies and errors in asset accounting.
  Cause:
  
  Duplicate Asset Numbers: The primary cause of this error is that the same asset number has been assigned to assets in different company codes. In SAP, asset numbers must be unique within a company code, but they can be reused across different company codes if not managed properly.
  Configuration Issues: There may be configuration settings in the asset accounting module that allow for the same asset number to be used across company codes, leading to conflicts during transactions.
  Data Migration Issues: If assets were migrated from another system or if there was a data upload, it is possible that the same asset numbers were inadvertently assigned to different company codes.
  
  Solution:
  
  Check Asset Numbers: Review the asset numbers in the affected company codes to identify duplicates. You can use transaction codes like AS03 (Display Asset) to check the asset details.
  Renumber Assets: If duplicates are found, you may need to renumber the assets in one of the company codes to ensure that each asset number is unique within its respective company code.
  Adjust Configuration: Review the configuration settings in the Asset Accounting module to ensure that asset number assignment rules are correctly set up to prevent duplication.
  Data Cleanup: If the issue arose from data migration, perform a cleanup of the asset data to ensure that each asset number is unique across company codes.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidelines on handling asset numbers and cross-company code transactions.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as AS01 (Create Asset), AS02 (Change Asset), and AS03 (Display Asset) for managing assets.
  SAP Notes: Check SAP Notes for any known issues or patches related to asset accounting and cross-company code transactions.
  User Exits and BAdIs: If custom logic is involved in asset number assignment, review any user exits or BAdIs that may affect how asset numbers are generated or validated.
  
  By addressing the root cause of the duplication and ensuring proper configuration and data management, you can resolve the CNVA_20290_CHECK079 error and prevent it from occurring in the future.
