• What is the cause and solution for SAP error message /SAPAPO/OM_TS100 - Changed object changed in a parallel transaction ?

  The SAP error message /SAPAPO/OM_TS100 indicates that a change was made to an object in a parallel transaction while you were trying to modify or access that same object. This is a common issue in SAP systems, particularly in environments where multiple users or processes are working on the same data simultaneously.
  Cause:
  
  Concurrent Access: The most common cause of this error is that two or more users or processes are trying to change the same object at the same time. For example, if one user is editing a planning object in SAP APO (Advanced Planning and Optimization) while another user is trying to save changes to the same object, the system will throw this error.
  Lock Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When one transaction locks an object, other transactions that attempt to modify that object will receive this error until the lock is released.
  Data Consistency: The system is designed to maintain data integrity and consistency, which is why it prevents changes to an object that has been modified by another transaction.
  
  Solution:
  
  Refresh the Data: If you encounter this error, the first step is to refresh your data. This can often be done by reloading the transaction or navigating away and back to the object you were working on.
  Check for Locks: Use transaction codes like SM12 to check for locks on the object. If you find that another user has locked the object, you may need to wait until they release the lock or coordinate with them to resolve the issue.
  Communicate with Users: If you are in a multi-user environment, communicate with your colleagues to ensure that you are not working on the same object simultaneously.
  Error Handling in Code: If you are developing custom code that interacts with SAP APO, implement error handling to catch this specific error and retry the operation after a brief pause.
  Transaction Management: Ensure that your transactions are managed properly, and avoid long-running transactions that may hold locks for extended periods.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error. Sometimes, there may be known issues or fixes provided by SAP.
  Documentation: Review the SAP APO documentation for best practices on handling concurrent transactions and data locking.
  System Performance: If this error occurs frequently, it may indicate performance issues in the system. Consider reviewing system performance and user activity to identify potential bottlenecks.
