  The SAP error message BRF350 ("No key fields found for structure &1") typically occurs in the context of Business Rule Framework (BRF) when the system is unable to identify key fields for a specified structure. This can happen for various reasons, and understanding the cause and finding a solution involves a few steps.
  Cause:
  
  Missing Key Fields: The structure specified in the error message does not have any key fields defined. Key fields are essential for uniquely identifying records in a structure.
