  The SAP error message AM361, which indicates a "System lock error," typically occurs in the context of Asset Accounting (FI-AA) when there is an attempt to post an asset transaction, but the system is unable to acquire the necessary locks on the relevant data. This can happen for several reasons, including concurrent access to the same asset by multiple users or processes, or issues with the database locks.
  Causes of AM361 System Lock Error:
  
  Concurrent Access: Multiple users or processes trying to access or modify the same asset simultaneously.
