  Meaning / Cause:
  This warning message occurs when a reference field specified in an expression or condition does not exist in the context where it is being used. Typically, this happens in ABAP programs, SAP Query, or when defining conditions or calculations in SAP tools like InfoSet queries, Logical Databases, or in the context of CDS views or other data retrieval mechanisms.
  The placeholders (&) in the message are replaced by actual values at runtime, indicating:
  
  The first &: The name of the reference field that is missing.
  The second &: The context or table alias where the field is expected.
  The third &: The expression or condition where the reference is used.
  
  In other words, the system cannot find the field you are trying to reference in the specified table or structure.
  
  Common Scenarios:
  
  Using a field in a condition or expression that is not part of the selected fields or the data source.
  Typographical errors in field names.
  Using fields from a table or structure that is not included in the join or data retrieval.
  In SAP Query or InfoSet, referencing a field that is not part of the InfoSet or Logical Database.
  In CDS views or Open SQL, referencing a field that does not exist in the underlying database table or view.
  
  
  How to Identify:
  
  Check the exact field name and spelling.
  Verify the data source or structure used in the expression.
  Check if the field is included in the select list or InfoSet.

  Solution / How to Fix:
  
  
  Verify Field Name:
  
  Ensure the field name is correct and exists in the table or structure you are referencing.
  
  
  Include the Field in Data Source:
  
  If you are using SAP Query or InfoSet, make sure the field is included in the InfoSet or Logical Database.
