• What is the cause and solution for SAP error message /SCMTMS/TOR_INT168 - One or more freight units or transportation units cannot be locked ?

  The SAP error message /SCMTMS/TOR_INT168 indicates that one or more freight units or transportation units cannot be locked. This typically occurs in the context of the SAP Transportation Management (TM) module when there is an attempt to process or modify freight units or transportation units that are currently being accessed or modified by another user or process.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing the freight unit or transportation unit, preventing your transaction from locking it.
  System Locking Mechanism: SAP uses a locking mechanism to ensure data integrity. If a unit is already locked by another transaction, you will receive this error.
  Long-Running Transactions: If a transaction is taking too long to complete, it may hold locks longer than expected, causing subsequent transactions to fail.
  Database Issues: Sometimes, database issues or inconsistencies can lead to locking problems.
  Configuration Issues: Incorrect configuration in the TM settings may lead to locking issues.
  
  Solutions:
  
  Check for Concurrent Users: Verify if another user is currently working on the same freight unit or transportation unit. If so, wait for them to complete their transaction.
  Transaction Monitoring: Use transaction codes like SM12 (to view and manage locks) to check for existing locks on the freight units or transportation units. You can identify the user or process holding the lock.
  Retry the Operation: After confirming that no other user is accessing the unit, try to perform the operation again.
  System Performance: If long-running transactions are common, consider optimizing the performance of your system or reviewing the processes that are taking too long.
  Database Consistency Check: If you suspect database issues, work with your database administrator to check for inconsistencies or issues that may be causing locking problems.
  Configuration Review: Review the configuration settings in SAP TM to ensure they are set up correctly and do not lead to unnecessary locking.
