• What is the cause and solution for SAP error message /SAPAPO/CTM1286 - Order selection &1 is being created by user &2 ?

  The SAP error message /SAPAPO/CTM1286 typically occurs in the context of the Advanced Planning and Optimization (APO) module, specifically during the Capacity Planning or Order Management processes. This error indicates that an order selection is being created by another user, which can lead to conflicts or inconsistencies in the planning process.
  Cause:
  
  Concurrent User Activity: The error is primarily caused by another user or process that is currently creating or modifying the same order selection. This can happen in environments where multiple users are working on the same planning data simultaneously.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When one user is working on a specific order selection, it locks that selection for other users until the first user completes their task.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their task. Once the lock is released, you can attempt to create the order selection again.
  Identify the User: If possible, identify the user who is currently working on the order selection. You can communicate with them to understand their timeline and coordinate your activities.
  Check for Background Jobs: Sometimes, background jobs or processes may also be holding locks. Check if there are any background jobs running that might be causing the lock.
  Transaction Monitoring: Use transaction codes like SM12 (to view and manage locks) to see if there are any active locks on the order selection. You can also use SM21 (System Log) to check for any related issues.
  System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and user roles to ensure that they are set up to minimize conflicts.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Review the SAP APO documentation for best practices on order management and user collaboration to avoid such conflicts.
  User Training: Ensure that users are trained on how to manage order selections effectively, including understanding the implications of concurrent access.
  
  If the problem persists despite following these steps, it may be necessary to involve your SAP Basis team or SAP support for further investigation.
