This error can arise due to various reasons, including issues with the configuration, data consistency, or system performance.
  Cause:
  
  Data Consistency Issues: There may be inconsistencies in the data being replicated, which can prevent the system from resetting the block data transfer flag.
  Configuration Errors: Incorrect settings in the SLT configuration can lead to this error. This includes issues with the source or target system configurations.
