• What is the cause and solution for SAP error message CNV_20100254 - 'Indicator: account managed in ext. syst.' of &1 differs from &2 in cc &3 ?

  The SAP error message CNV_20100254 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates a discrepancy between the account management settings in the source system and the target system for a specific account in a particular company code.
  Cause:
  The error message "Indicator: account managed in ext. syst. of &1 differs from &2 in cc &3" suggests that:
  
  The account in question is set to be managed in an external system in one of the systems (either the source or the target).
  The settings for account management (e.g., whether the account is managed in an external system or not) differ between the two systems for the specified company code.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Account Settings:

  Adjust Settings:
  
  If the settings differ, you will need to decide which setting is correct based on your business requirements. You may need to adjust the settings in either the source or target system to ensure they match.
  If the target system should manage the account in an external system, ensure that the corresponding settings are updated in the source system before migration.
  
  
  
  Data Mapping:
  
  Review the data mapping and transformation rules in your migration project. Ensure that the account management indicators are correctly mapped.
