• What is the cause and solution for SAP error message CNV_20200_CHECK158 - Duplicate asset numbers will occur for the participating company codes ?

  The SAP error message CNV_20200_CHECK158 indicates that there is a potential issue with duplicate asset numbers across different company codes during a data migration or conversion process. This error typically arises in the context of the SAP S/4HANA migration or during the use of the SAP Asset Accounting module.
  Cause:
  The error occurs when the system detects that the same asset number is being used for different company codes. In SAP, asset numbers must be unique within a company code. If the same asset number is assigned to multiple company codes, it can lead to inconsistencies and errors in asset accounting.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicate Asset Numbers:
  
  Use transaction codes like SE16 or SE11 to query the asset master data tables (e.g., ANLA, ANLB) to identify which asset numbers are duplicated across company codes.
  
  
  
  Renumber Assets:
  
  If duplicates are found, you will need to renumber the assets in one of the company codes. This can be done by creating new asset numbers for the affected company codes and ensuring that they are unique.
  
  
  
  Adjust Migration Data:
  
  If you are migrating data, ensure that the data being imported does not contain duplicate asset numbers across company codes. You may need to modify your migration files or scripts to ensure uniqueness.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the Asset Accounting module to ensure that the asset number ranges are set up correctly and do not overlap across company codes.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test run of the migration or conversion process to ensure that the error does not reoccur.
  
  
  
  Consult Documentation:
  
  Refer to SAP Notes and documentation related to asset accounting and data migration for any specific guidelines or recommendations.
