  SAP Error Message:
  WP306 - Upload document & does not contain any header segment
  
  
  Cause:
  This error occurs during the upload of a document (usually via batch input, IDoc, or other data transfer methods) when the system expects a header segment in the document structure but does not find it. The "header segment" is a mandatory part of the document that contains key information such as document type, date, and other control data.
  Common causes include:
  
  The uploaded file or data structure is incomplete or incorrectly formatted.
  The header segment is missing or corrupted.
  Incorrect mapping or configuration in the data upload process.
  The interface or middleware sending the document is not including the header segment.
  
  
  
  Solution:
  
  
  Check the Upload File/Structure:
  
  Verify that the document being uploaded contains the header segment.
  Ensure the file format and structure comply with SAP's expected format.
  If using IDocs, check that the EDI segments include the mandatory header segment (e.g., E1EDK01 for IDoc ORDERS).
