• What is the cause and solution for SAP error message VK20026 - Program error: Item without header (GUID &1, POSNR = &2) ?

  The SAP error message VK20026, which states "Program error: Item without header (GUID &1, POSNR = &2)," typically occurs in the context of sales and distribution (SD) or pricing procedures. This error indicates that there is an issue with the data integrity of a document, where an item is being referenced without a corresponding header.
  Cause:
  
  
  Data Integrity Issues: The most common cause of this error is that the item (POSNR) is being referenced in the system without a valid header (GUID). This can happen due to:
  
  Incomplete document processing.
  Manual changes to the document that led to a mismatch between the header and item data.
  Data corruption or inconsistencies in the database.
  
  
  
  Custom Code or Enhancements: If there are custom programs, user exits, or enhancements that manipulate sales documents, they might inadvertently create situations where items are processed without their corresponding headers.
  
  
  System Bugs: Occasionally, this error can be triggered by bugs in the SAP system or specific patches that have not been applied.
  
  
  Solution:
  
  
  Check Document Consistency: 
  
  Use transaction codes like VA03 (Display Sales Order) or VF03 (Display Billing Document) to check the document in question. Ensure that the header and item data are consistent and that the item exists under the correct header.
  
  
  
  Recreate the Document: If the document is corrupted, it may be necessary to recreate it. This can involve:
  
  Deleting the problematic document (if possible) and creating a new one.
  If the document is already posted, consider reversing it and then creating a new one.
  
  
  
  Review Custom Code: If there are custom developments, review the code to ensure that it correctly handles the relationship between headers and items. Debugging the custom code may help identify where the issue arises.
  
  
  SAP Notes and Support: Check for any relevant SAP Notes that might address this specific error. Sometimes, SAP releases patches or notes that provide fixes for known issues.
  
  
  Consult SAP Support: If the issue persists and cannot be resolved through the above steps, consider reaching out to SAP Support for assistance. Provide them with the error details, including the GUID and POSNR, to help them diagnose the issue.

  Transaction Codes: Familiarize yourself with transaction codes related to sales documents, such as VA01 (Create Sales Order), VA02 (Change Sales Order), and VA03 (Display Sales Order).
  Debugging: If you have access to debugging tools, you can set breakpoints in the relevant programs to trace the execution flow and identify where the error occurs.
  Data Consistency Checks: Regularly perform data consistency checks in your SAP system to prevent such issues from arising in the future.
