• What is the cause and solution for SAP error message CNV_00001232 - In table &1 all fields are marked as read-only; table ignored. ?

  The SAP error message CNV_00001232 indicates that all fields in a specified table (denoted as &1) are marked as read-only, which means that the system cannot perform any operations (like data migration or transformation) on that table. This error typically arises during data migration processes, especially when using tools like SAP S/4HANA Migration Cockpit or other data transfer methods.
  Cause:
  
  
  Read-Only Table: The table in question is configured as read-only in the system. This could be due to various reasons, such as:
  
  The table is a system table or a configuration table that should not be modified.
  The table is locked for data changes due to ongoing processes or settings in the system.
  The table is part of a data model that restricts changes to ensure data integrity.
  
  
  
  Incorrect Configuration: The migration or transformation process may be incorrectly configured, leading to the system interpreting the table as read-only.
  
  
  Authorization Issues: The user executing the migration may not have the necessary authorizations to modify the table, leading to it being treated as read-only.
  
  
  Solution:
  
  
  Check Table Properties: Verify the properties of the table in the Data Dictionary (SE11) to confirm if it is indeed marked as read-only. If it is a custom table, you may need to adjust its properties.
  
  
  Review Migration Settings: Ensure that the migration settings are correctly configured. Check if the table is included in the migration scope and that the mapping is correctly defined.
  
  
  User Authorizations: Ensure that the user executing the migration has the necessary authorizations to modify the table. You may need to consult with your SAP security team to verify and adjust the user's roles and permissions.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using. There may be specific guidelines or prerequisites for handling certain tables.
  
  
  Contact SAP Support: If the issue persists and you cannot determine the cause, consider reaching out to SAP Support for assistance. They can provide insights based on the specific context of your system and the migration process.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE37 (Function Modules), and ST22 (Dump Analysis) to investigate further.
  SAP Notes: Search for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
