BOM Web Example

The Summarized BOM for an item describes all the parts and their total quantity required in the production of the item. For each component, the Summarized BOM lists the following information:

The Summarized BOM for the 5-Gal Tank Assembly in the BOM Web example is shown in Figure A.8. Chapter 4 describes a macro, %BOMRSUB , that constructs a summarized bill of material for a selected item.

The Gross Requirement Summary for an item lists the quantities of all components needed to produce the required quantity of the item. This report enables you to analyze how future orders for an item will impact inventory levels. See the section Summarized Parts Data Set and Example 3.9 in Chapter 3 for details about the gross requirement calculation.

For each component, the Gross Requirement Summary includes the following:

Figure A.9 shows the Gross Requirement Summary report for the 5-Gal Tank Assembly with a required quantity of 40. Notice that this report is similar to the Summarized BOM in Figure A.8, with a column "Gross Req." that is 40 times the "Qty. Required" column from the Summarized BOM. The Gross Requirement Summary also includes a column for quantity on hand for inventory status information to compare with component requirements.

The Single-Level Where-Used report for an item lists each parent in which that item is directly used and in what quantity. For each parent item, the Single-Level Where-Used report lists the following:

The Single-Level Where-Used report for the Clamp is shown in Figure A.10. Chapter 4 describes a macro, %BOMRSLW , that constructs a single-level where-used list for a selected item.

The Indented Where-Used report for an item traces its use through the indented bill of material. This report lists the item and steps through each higher-level component or assembly using the item until a final product is reached. At each level, for the current part or assembly, the Indented Where-Used report lists the following:

The Indented Where-Used report for the Clamp is shown in Figure A.11. Chapter 4 describes a macro, %BOMRMLW , that constructs an indented where-used list for a selected item.

In addition, the %BOMRSUW macro can be used to construct a summarized where-used list for a selected item, which lists the total usage of this item for every higher-level parent using it. See Chapter 4 for more information on these BOM reporting macros.
