• What is the cause and solution for SAP error message /SAPAPO/OM030 - Order cannot be dispatched at determined times due to parallel change ?

  The SAP error message /SAPAPO/OM030 indicates that an order cannot be dispatched at the determined times due to a "parallel change." This typically occurs in the context of Advanced Planning and Optimization (APO) when there are conflicting changes being made to the order or its related components.
  Cause:
  
  
  Concurrent Changes: The error usually arises when multiple users or processes are trying to change the same order or related data simultaneously. This can happen in scenarios where:
  
  An order is being modified while another process is trying to dispatch it.
  Changes to the order's components (like operations, resources, or scheduling) are being made at the same time.
  
  
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If one user has locked the order for editing, another user trying to dispatch it will encounter this error.
  
  
  Scheduling Conflicts: If the order's scheduling is being altered (e.g., changing start/end times, resources, etc.) while another process is trying to dispatch it, this can lead to conflicts.
  
  
  Solution:
  
  
  Check for Concurrent Changes: Ensure that no other users or processes are trying to modify the same order at the same time. Communicate with your team to coordinate changes.
  
  
  Release Locks: If you suspect that a lock is causing the issue, you can check the lock entries using transaction code SM12. Identify and release any unnecessary locks, but be cautious as this can lead to data inconsistencies if not handled properly.
  
  
  Retry Dispatching: After ensuring that no other changes are being made, try to dispatch the order again.
  
  
  Review Order Status: Check the status of the order to ensure it is in a state that allows dispatching. If the order is in a "locked" or "in-process" state, it may need to be completed or released first.
  
  
  System Logs: Review system logs or application logs for any additional error messages or warnings that might provide more context about the issue.
  
  
  Consult Documentation: Refer to SAP documentation or support notes related to this error message for any specific guidance or patches that may address the issue.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO02 (Change Production Order), CO03 (Display Production Order), and SM12 (Display and Delete Locks).
  User Roles: Ensure that users have the appropriate roles and permissions to make changes to orders and dispatch them.
  SAP Notes: Check for any SAP Notes that may address known issues related to this error message.
