The SAP error message CNV182, which states "The field already exists, or the table contains no such field," typically occurs during data migration or conversion processes, particularly when using SAP's Data Migration tools or during the execution of certain programs that manipulate database tables.
Cause:
Field Already Exists: This part of the error indicates that the system is trying to add a field to a table that already has that field defined. This can happen if the migration process is attempting to create a field that was previously created in a prior step or if the field was manually added to the table outside of the migration process.
Table Contains No Such Field: This indicates that the system is trying to reference a field that does not exist in the specified table. This could be due to a typo in the field name, an incorrect table reference, or a mismatch between the source and target structures during the migration.
Solution:
Check Field Existence: Verify if the field in question already exists in the target table. You can do this by checking the table structure in the Data Dictionary (transaction SE11) to see if the field is already defined.
Review Migration Logic: If the field already exists, review the migration logic to ensure that it does not attempt to create the field again. You may need to adjust the migration scripts or configurations to prevent this duplication.
Correct Table and Field Names: If the error indicates that a field does not exist, double-check the spelling and naming conventions used in your migration scripts. Ensure that the field names match exactly with those defined in the target table.
Check for Table Changes: If the target table structure has been modified (e.g., fields added or removed) after the migration scripts were created, you may need to update the scripts to reflect these changes.
Consult Documentation: If you are using a specific migration tool or program, consult the relevant SAP documentation or notes for guidance on how to handle this error.
Debugging: If you have access to debugging tools, you can step through the migration process to identify exactly where the error occurs and gather more context about the issue.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
