MY428 - Details

• The SAP error message MY428, which states "Delta run cannot be locked," typically occurs in the context of the SAP BW (Business Warehouse) system during the execution of delta loads. This error indicates that the delta process is unable to acquire a lock on the data that it needs to process, which can prevent the delta load from completing successfully.
  Causes:
  
  Concurrent Delta Loads: If multiple delta loads are trying to run simultaneously for the same data source, one may block the other from acquiring the necessary locks.
  Long-Running Processes: A long-running process or a previous delta load that has not yet completed can hold the lock, preventing new delta runs from starting.
  System 
  Configuration Issues: Misconfigurations in the data source or the extraction process can lead to locking issues.
  Database Locks: Locks at the database level can also cause this issue, especially if there are transactions that are not being released properly.
