• What is the cause and solution for SAP error message ARUN_MAIN168 - Items will be locked at material/plant( MARC ) level. ?

  The SAP error message ARUN_MAIN168 indicates that items are locked at the material/plant (MARC) level. This typically occurs when there are concurrent processes trying to access or modify the same material data in the system, leading to a lock situation. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same material data simultaneously.
  Long-Running Transactions: A transaction that takes a long time to complete can hold locks longer than expected, causing other transactions to wait.
  Background Jobs: Background jobs that are processing material data can also lead to locks if they are not managed properly.
  Database Locks: Locks at the database level can occur due to various reasons, including uncommitted transactions or deadlocks.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify Locking Sessions: Use transaction codes like SM12 (Display and Delete Locks) to identify which user or process is holding the lock. You can then decide whether to wait for the lock to be released or contact the user to resolve the issue.
  Check Background Jobs: Use transaction code SM37 to check for any background jobs that might be causing the lock. If necessary, you can stop or adjust these jobs.
  Optimize Transactions: Review the transactions that are causing locks and optimize them to reduce the time they hold locks. This may involve breaking down large transactions into smaller ones or improving performance.
  Lock Management: Ensure that your system is configured properly for lock management. This includes reviewing the lock parameters and settings in the system.
  Database Administration: If the issue persists, it may be necessary to involve your database administrator to check for any underlying database issues that could be causing excessive locking.
