The Backflush Operations command tells DMS to “backflush” from a given operation back to the beginning of the job and set the status of all the previous operations to a given status.  For example, a job has the following operations with various statuses: 

       10        I

       20        Q        

       30        I

       40

       50        C

       60        I

       70

       80

       90

The user then updates operation 70 to be C for complete and requests a backflush of all previous operations to also be set to C.  After the update the job would be as follows:

       10        C

       20        C        

       30        C

       40        C

       50        C

       60        C

       70        C

       80

       90

The backflush command is a handy way to make sure that all previous operations to a given operation are completed.
