• What is the cause and solution for SAP error message DG112 - Change number collision following update ?

  The SAP error message DG112, which states "Change number collision following update," typically occurs in the context of change management within SAP systems, particularly when dealing with change numbers in the context of the SAP Change and Transport System (CTS) or when managing configuration changes in the system.
  Cause:
  The error usually arises when there is a conflict between change numbers during an update. This can happen due to several reasons:
  
  Concurrent Changes: Multiple users or processes are trying to update the same object or configuration at the same time, leading to a collision in change numbers.
  Transport Requests: If multiple transport requests are being processed simultaneously and they reference the same change number, it can lead to this error.
  System Configuration: Misconfiguration in the change management settings or issues with the transport directory can also lead to this error.
  
  Solution:
  To resolve the DG112 error, you can take the following steps:
  
  
  Check for Concurrent Updates: Ensure that no other users or processes are trying to update the same object at the same time. If possible, coordinate with your team to avoid simultaneous updates.
  
  
  Review Change Numbers: Check the change numbers involved in the update. You can do this by using transaction codes like SE01 (Transport Organizer) or SE09 (Workbench Organizer) to see the transport requests and their statuses.
  
  
  Release Transport Requests: If you have transport requests that are in a "modification" state, consider releasing them to avoid conflicts. This can be done in SE01 or SE09.
  
  
  Check Transport Directory: Ensure that the transport directory is correctly configured and that there are no issues with the transport files. You can check the transport directory settings in transaction code STMS.
  
  
  System Logs: Review system logs for any additional error messages or warnings that might provide more context about the collision. You can use transaction SM21 to view the system log.
  
  
  Consult Documentation: Refer to SAP Notes or documentation related to change management and transport issues. SAP Notes may provide specific fixes or patches for known issues.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They can provide more detailed troubleshooting based on your specific system configuration.

  Change Management Best Practices: Familiarize yourself with best practices for managing changes in SAP systems to minimize the risk of collisions and errors.
  Transport Management System (TMS): Understanding how TMS works can help you manage transports more effectively and avoid conflicts.
