  The SAP error message /PF1/MSG_PO_EH016 indicates that there is a duplicate submission of a Purchase Order (PO). This error typically arises in scenarios where a PO is being processed multiple times, which can happen due to various reasons such as network issues, user errors, or system configurations.
  Cause:
  
  Duplicate Submission: The most common cause is that the same PO is being submitted more than once, either by the same user or by different users.
  Network Issues: If there are network interruptions during the submission process, the system might not receive confirmation of the first submission, leading users to attempt resubmission.
  System Configuration: Certain configurations in the SAP system may allow for duplicate submissions under specific conditions.
  User Error: Users may inadvertently click the submit button multiple times, leading to duplicate requests.
  
  Solution:
  
  Check for Existing PO: Before submitting a new PO, check if the PO already exists in the system. You can do this by searching for the PO number in the relevant transaction (e.g., ME23N for display).
  Review Submission Process: Ensure that the submission process is clear to users to avoid accidental duplicate submissions. Consider implementing a confirmation step before final submission.
  Network Stability: Ensure that the network connection is stable during the submission process to avoid interruptions that could lead to duplicate submissions.
  System Configuration Review: Consult with your SAP Basis or technical team to review the system configuration and ensure that it is set up to handle duplicate submissions appropriately.
  Error Handling: Implement error handling in the application layer to catch and manage duplicate submissions gracefully.
