• What is the cause and solution for SAP error message CNV_40301021 - New acct. det. &1 is neither in the mapping nor in the value table ?

  The SAP error message CNV_40301021 indicates that a new account determination (accounting document) is not found in the mapping or value table during a data migration or conversion process. This typically occurs in the context of using SAP's Migration Cockpit or during data transfer processes where account mappings are required.
  Cause:
  
  Missing Mapping: The account determination you are trying to use has not been mapped in the system. This means that the system does not know how to handle this specific account in the context of the migration.
  Incorrect Configuration: The configuration settings for the mapping might be incorrect or incomplete, leading to the system not recognizing the account.
  Data Issues: The data being migrated may contain accounts that do not exist in the target system or are not properly defined in the mapping tables.
  Value Table Issues: The value table that should contain the necessary account information may not be populated correctly or may be missing entries.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the relevant mapping transaction (e.g., transaction code OBY6 for account determination) and verify that the account in question is correctly mapped.
  Ensure that the mapping table includes the new account determination.
  
  
  
  Update Value Tables:
  
  Ensure that the value tables are populated with the necessary account information. You may need to add the missing account to the value table manually if it is not present.
  
  
  
  Review Migration Settings:
  
  If you are using the SAP Migration Cockpit, review the migration settings and ensure that all necessary mappings are defined.
  Check if there are any specific migration templates or guidelines that need to be followed.
