  • Product Structure Filter Enhancement
    Business Case
    Customer demand is dynamic; that is, schedulers constantly face increasing/decreasing order quantities, new orders entries, and changes in order dates. In mid- to long-term planning and scheduling, MRP assists a scheduler with these dynamic changes by updating the planned production orders, time-phased across all levels of the product structure; however, once the scheduler firms those planned orders, MRP no longer has the authority to change the orders. In these situations, the scheduler must manually update the firm orders that are impacted by changes in customer demand.
    To make changes across all product structure levels that relate to a change at the parent level—the finished item level—schedulers typically had to go through many multi-level planning cycles to make updates. When a product has a bill of materials (BOM) that is two or more levels deep, schedulers had no way to:
    Quickly determine the demand impact on the dependent lower levels.
    Efficiently update the schedules across all levels of the BOM impacted by the change.
    Perform an update for just a single item and the related dependent items, which could take considerable time. Dozens of such updates can be performed every day.
    With the version of the workbenches, schedulers can use the new Product Structure Filter to gauge the impact of the change immediately for all levels of the BOM. The MSW Schedule Grid includes the Product Structure Filter (see Schedule Grid Product Structure Filter).
    With a single click, schedulers can render all levels of an item—both up and down—within the Schedule Grid. When schedulers click the Product Structure Filter, the filter turns red and the MSW Schedule Grid provides immediate visibility to all items and item schedules related to the selected item. Schedulers can quickly visualize QOH as well as the PQOH for each component across the BOM for the scheduled production order, letting them quickly gauge the impact of the change for lower levels. When the scheduler clicks the Product Structure Filter again, the BOM levels are removed from the Schedule Grid.

    Schedule Grid Product Structure Filter
    To determine BOM levels, select to display the Levels column in the Schedule Grid by right-clicking on any column header in the Schedule Grid, then selecting Columns, and Levels. When levels display in the grid, you can determine the product hierarchy. A level 0 (zero) is the main item, while a 1 is one upper level, a 2 is two upper levels, and -1 is one lower level, -2 is two lower levels, and so on.

    Product Structure Levels
    Levels and Search Results
    The search process may result in only a subset of BOM components and levels. So, for example, if you search for a finished item and a component item that is five levels down the BOM, you may only see two items that display in the Schedule Grid.
    This is because your original search criteria did not include all components and the product structure filter can only display components that are available, based on the criteria you set for the search.
