  Cause:
  This message occurs during the processing of a goods movement or inventory transaction (such as a goods issue, goods receipt, transfer posting, or physical inventory) when the system detects that the document or item you are trying to process has been changed by another user or process since you last accessed it.
  Specifically, the system compares the current status of the document type, document number, item number, and material number with the data you have. If any of these have been modified (e.g., quantity changed, item deleted, document updated), the system raises this message to prevent inconsistencies or data conflicts.
  
  When does it typically occur?
  
  During posting of goods movements (e.g., MIGO, MB1A, MB1B, MB1C transactions).
  When multiple users/processes are working on the same material document or inventory document
