  The SAP error message KV641 ("Key fields in the list cannot be deleted") typically occurs when you are trying to delete or modify key fields in a list or table that are essential for maintaining data integrity.

  Review Key Fields: Check the list or table you are working with to identify which fields are designated as key fields. Understand their role in the data structure.
