The DWC/WCIS defines each ST-SE transaction set to be one batch. The WCIS compares the batch control number, original transmission date, original transmission time, sender FEIN, and the sender postal code to all other batches previously reported to the WCIS to detect duplicate batches. When the same data values for all the above-listed data elements occur, the WCIS puts the 057 error in the LQ segment and the phase “Duplicate Batch Header” in the RED segment containing the bad data field in the 824 detailed acknowledgment.
