  The SAP error message /PF1/MSG_PO_EH030 typically indicates that there is an issue with locking during the duplicate order check process in the Purchase Order (PO) creation or modification. This error can occur when the system is trying to ensure that no duplicate purchase orders are created, but it encounters a locking issue.
  Cause:
  
  Locking Issues: The error often arises when multiple users or processes are trying to access the same purchase order or related data simultaneously, leading to a lock conflict.
  Database Lock: The database may have a lock on the table or record that is being accessed, preventing the current transaction from proceeding.
  Long-running Transactions: If a previous transaction is taking too long to complete, it may hold a lock longer than expected, causing subsequent transactions to fail.
  Configuration Issues: There may be configuration settings in the system that are not set up correctly, leading to issues with the duplicate order check process.
  
  Solution:
  
  Wait and Retry: If the error is due to a temporary lock, waiting for a few moments and then retrying the operation may resolve the issue.
  Check for Active Sessions: Use transaction codes like SM12 to check for active locks in the system. If you find locks that are no longer needed, you can release them (with caution).
  Review Long-running Transactions: Identify any long-running transactions that may be holding locks and address them. This may involve optimizing the transaction or checking for issues in the related processes.
