  The SAP error message /SAPAPO/FOT612 Order &1 of &2 is locked by other session. Try again later. typically occurs in the SAP Advanced Planning and Optimization (APO) module when a user attempts to access or modify an order that is currently locked by another session. This locking mechanism is in place to prevent data inconsistencies that could arise from simultaneous modifications.
  Cause:
  
  Concurrent Access: Another user or session is currently accessing or modifying the same order.
  Long-Running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected.
  System Issues: Sometimes, system issues or bugs can lead to locks not being released properly.
  Background Jobs: Background jobs that are processing the same data can also cause locks.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for a few moments and then try again. The lock may be released once the other session completes its operation.
  Identify the Lock: Use transaction code SM12 to check for locks. You can look for the specific order number and see which user or session is holding the lock.
  Contact the User: If you identify the user holding the lock, you can contact them to see if they can release the lock or complete their transaction.
  Release the Lock: If necessary and if you have the appropriate authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies.
  Check for Background Jobs: Use transaction SM37 to check if there are any background jobs that might be locking the order. If so, you may need to wait for those jobs to complete.
  System Monitoring: If this issue occurs frequently, it may be worth investigating the system performance and user activity to identify any patterns or issues that need to be addressed.
