  Cause:
  This error typically occurs in SAP Retail (IS-Retail) or related modules when attempting to post a void receipt (i.e., cancel or reverse a previously posted receipt document), and the system cannot find the corresponding transaction header record in the database.
  In other words, the system expects a transaction header (which contains the main details of the original receipt document) to exist for the receipt you are trying to void, but it is missing or has been deleted/corrupted.
  Common reasons include:
  
  The original receipt document was not properly posted or was deleted.
  Database inconsistencies or missing entries in the transaction header tables (e.g., table POS_TRANSACT or related).
  Incorrect or incomplete data entry during the void process.
  Custom enhancements or user exits that interfere with the standard posting logic.
  
  
  
  Solution:
  
  
  Verify the Original Receipt Document:
  
  Check if the original receipt document exists and is correctly posted.
  Use transaction codes like POSDW
