• What is the cause and solution for SAP error message CNVA_20000_ANALYSIS031 - Unknown types in AWTYP fields ?

  The SAP error message CNVA_20000_ANALYSIS031 with the description "Unknown types in AWTYP fields" typically occurs during the conversion or migration of data, particularly when dealing with the Asset Accounting (FI-AA) module. This error indicates that there are unknown or unrecognized asset types (AWTYP) in the data being processed.
  Cause:
  
  Invalid Asset Type: The error is often caused by the presence of asset types in the data that do not exist in the target system or are not defined in the configuration.
  Data Migration Issues: During data migration, if the mapping of asset types from the source system to the target system is not done correctly, it can lead to this error.
  Configuration Issues: If the asset types have not been properly configured in the target system, the system will not recognize them.
  
  Solution:
  
  
  Check Asset Type Configuration:
  
  Go to the configuration settings in the target SAP system and verify that all asset types (AWTYP) used in the source system are defined in the target system.
  You can check this in the Asset Accounting configuration under Financial Accounting (FI) > Asset Accounting > Master Data > Define Asset Classes.
  
  
  
  Data Mapping:
  
  Review the data mapping used during the migration process. Ensure that all asset types from the source system are correctly mapped to the corresponding asset types in the target system.
  If there are new asset types in the source system that do not exist in the target system, you may need to create them.
  
  
  
  Data Validation:
  
  Before executing the migration, validate the data to ensure that all asset types are recognized. This can be done by running a report or using a data validation tool to check for discrepancies.
  
  
  
  Error Logs:
  
  Check the error logs for more detailed information about which specific asset types are causing the issue. This can help in identifying the missing or unrecognized types.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to asset accounting and data migration for any specific guidelines or updates that may address this issue.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test migration to ensure that the error does not occur again.
