There are three main components to the data used to maintain bills of material and evaluate effects of planned orders: Part Master File, Product Structure File, and Planned Orders. This example illustrates typical forms of these data elements.

The data for the BOM Web example are directly related to the data sets required for the BOM procedure, as discussed in Chapter 3: The BOM Procedure. The Part Master File and Planned Orders file together correspond to the PMDATA= data set, and the Product Structure File corresponds to the DATA= data set. Refer to Chapter 3 for more information about these data sets and PROC BOM.
