  Deadlocks: Situations where two or more transactions are waiting for each other to release locks can lead to this error.
  Lock Configuration: The configuration of the database or the application may not be optimized for the workload, leading to excessive locking.
  
  
  Solution:
  
  
  Identify Blocking Transactions:
  
  Use transaction codes like SM12 (for lock entries) to identify which user or process is holding the lock on the table.
