Setback Days

The following diagram illustrates the routing information in the Bill of Resources Example, as well as setback days for each department resource combination. Setback days represents the number of days before the completion of an item that a particular resource requirement is needed. In this example, C's lead time is 2 days. D1, R2 is needed at the start of operation 20 on day 2. The setback days for the resource requirement for D1, R2 is therefore 1 day.

Setback days are calculated using the resource offset percent and item lead times calculated by the Oracle Work in Process scheduler during the Oracle Bills of Material lead time rollup process.

The following table illustrates the bills of resources that the bill of resources load would generate for A, B, and C based on the bill of material and routing information detailed in the previous tables. These are used by routing and rate-based RCCP to calculate resource requirements for master schedule entries. Cumulative resource requirements are show in bold.
