  The SAP error message I4645 "Data records unlocked; lock object &1 (&2)" typically indicates that a data record you are trying to access is currently unlocked, meaning that the system has detected that the record is not locked for editing or processing. This can occur in various scenarios, particularly when dealing with data records in SAP applications that utilize lock objects to manage concurrent access.
  Cause:
  
  
  Record Not Locked: The primary cause of this error is that the data record you are trying to access is not locked. This can happen if:
  
  The record was previously locked by another user or process, but the lock has been released.

  Incorrect Lock Object: The lock object specified in the error message may not correspond to the data record you are trying to access.
  
  
  Timing Issues: If there are timing issues in the system, such as a delay in the lock being established or released, you may encounter this error.
  
  
  Solution:
  
  
  Check Lock Status: Verify the lock status of the data record. You can use transaction code SM12 to check for existing locks and see if the record is currently locked by another user.
  
  
  Reattempt the Operation: If the record is unlocked, you can simply reattempt the operation. Sometimes, the error may be transient.
  
  
  Review Lock Object Configuration: Ensure that the lock object configuration is correct. This may involve checking the relevant ABAP code or configuration settings to ensure that the lock object is being used properly.
