WER271 - Details

• The SAP error message:
  WER271: Item field with id &1 is not a data element
  
  
  Cause:
  This error occurs when a field (item field) in a message or a data dictionary object is expected to be a data element, but the system finds that the field is not defined as a data element. In SAP ABAP Dictionary, fields in structures, tables, or messages are typically defined using data elements to ensure semantic consistency and reuse of domain definitions.
  In other words, the field identified by &1 (the placeholder replaced by the actual field name at runtime) is not linked to a data element but might be a direct elementary type or some other object type, which is not allowed in the context where the system expects a data element.
  
  When does this happen?
  
  When defining message types in ALE/IDoc processing, the segments or fields must be linked to data elements.
  When creating or modifying structures or tables
