Cost roll-up enables you to calculate the costs of manufacturing an item. Because QAD Configurator adds the product structure of any items that you configure to the QAD Enterprise Applications database, the cost roll-up functionality is incorporated in QAD Configurator as well.

Calculating the costs for an item involves adding the following five types of costs:

The roll-up of the total costs consists of a routing cost roll-up and a product structure cost roll-up. Refer to the relevant QAD Enterprise Applications user guides for a detailed description of routing and product structure cost roll-up.

During configuration of a variant, QAD Configurator calculates the costs of manufacturing the item. To see these costs, run Product Structure Cost Report (13.12.4) in the Manufacturing module for items 01040, 50020 and the variant items. Enter the correct site (10-100) and the correct cost set (Standard).

You can also use Item Master Maintenance (1.4.1) in the Master Data module to see the costs associated with items.

As we have seen, you can use Element Roll-Up Maintenance to calculate non-cost data. The roll-up calculation is made during the process of creating a variant product structure and/or a variant routing and the outcome is stored in a field belonging to this variant.

Element Roll-Up allows us to execute a calculation afterwards — that is, after the variant product structure or routing has been created. For example, you want to change the original formula that was used in the calculation.

Before you can run Element Roll-Up, first define the element roll-up rules for configurable items. The input to Element Roll-Up can either be variant items or configurable items for which you want to update all variants.
