Understanding CUM Rollback

You can use cumulative rollback to automatically reset cumulative quantities to zero for values that are incremental. When you reset cumulative values, the system updates current cumulative values for each item to reflect all activity occurring since the beginning of the period. The system displays the updated values on the applicable fields on the CUM Shipped, Firm CUM Required, Plan CUM Required, and Prod. Seq. CUM Required tabs on the CUM Revisions form.

When using cumulative rollback, you manually select a set of records based on a cumulative model combination to roll back the values. You specify the date to which you want the information reset and which adjustment codes you want to include in the rollback.

You can review the details of the rollback. The system displays all of the cumulative records within the selected model. You cannot update information when reviewing the details on the CUM Rollback Detail form. You can also run this report in Proof mode.

When you reset values, the system runs the Rollback CUMs program (R40R020), which resets cumulative values to zero and calculates the adjusted values for the CUM shipped and required fields.

If you set the CUM Rollback (P40R421) processing options to run the report, the system displays the On Report Output Destination form. Specify the report destination and click OK.
