  The SAP error message EBR429, which states "Error while locking inspection lot &1," typically occurs during the inspection lot processing in the Quality Management (QM) module. This error indicates that the system encountered an issue while trying to lock the specified inspection lot for processing, which is necessary to prevent concurrent changes by multiple users or processes.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing or modifying the inspection lot, leading to a lock conflict.

  Solutions:

  System Monitoring: Use transaction codes like SM12 (to check for locks) and SM21 (to check system logs) to identify any locks or issues in the system.
