• What is the cause and solution for SAP error message HOSHABA821 - Table &1 (key: &2) has already been locked by user &3 ?

  The SAP error message HOSHABA821 indicates that a specific table (denoted by &1) with a particular key (denoted by &2) is currently locked by another user (denoted by &3). This typically occurs when multiple users or processes attempt to access or modify the same data simultaneously, leading to a lock situation to maintain data integrity.
  
  Cause:
  
  Concurrent Access: Another user or process is currently accessing or modifying the same record in the specified table.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on the table longer than expected.
  Uncommitted Changes: If a user has made changes to the data but has not yet committed those changes, the lock will persist.
  Deadlocks: In some cases, a deadlock situation may arise where two or more processes are waiting for each other to release locks.
  
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to complete their transaction
