Master Control Record (MCR)
This is basically the DLN and ABC identifier along with other block header information of a given block. This data is gathered through input from DIS, OCR, RPS and IDRS to create the block on the SCCF. This allows for identification of a block of work from its inception. If the block is lost, the SCCF will possess the original DLN as an audit trail.
