From purchasing, manufacturing, assembling, and ultimately selling products, keeping track of the entire production process stage-by-stage can be a challenge. Many small to midsized enterprises that use project resource planningapplications, like SAP Business One, have found that having Bill of Materials at their disposal can help them overcome these common production related challenges; making the overall production process much more efficient, accurate, and timely.
For many companies, the production process starts with raw materials and the creation of a production order which contains all of the materials and steps required to produce an item within a predefined time frame. The materials compulsory for a production order can be found in the BOM generated by SAP Business One. The BOM contains a hierarchical arrangement of components that lists all of the raw materials and child or sub items required to assemble and produce a finished product.
The 4 Bill of Material types in SAP Business One
In order to get the nearly all out of the 4 different BOM types in SAP Business One, they must first be explained. Here are 4 BOM types that can be generated using SAP Business One:
Production Bill of Material
For all Materials Requirements Planning (MRP) runs and standard production guidelines, a Production BOM is required. The Production BOM lists parent items which are finished products and the child items are components which complement the parent item. During the production process you can turn components into finished products.
Sales Bill of Material
A Sales BOM is used for sales documents where the parent item is listed only as a sales item, not an inventory item. Once the parent is selected in the sales document all of the children appear as sub-items. You can update the quantities of the parent or children, but you cannot delete children or add new children or sub-items to the package in the sales essay. An example of this would be a computer printer and its components where the parent would be the package or sales item and the children would be the inventory items inside the package.
Assembly Bill of Material
An Assembly BOM is similar to the Sales BOM as it represents a collection of individual items in a set with a specific price. Much the same with the Sales BOM, you do not manage the final product as an inventory item, but rather as a sales item. But, unlike the Sales BOM, only the finished product appears in the sales article, the components do not appear as sub-items.
Template Bill of Material
A Template BOM has no real restrictions and is flexible; the parent and child can be any type of item. This type of BOM can be used in both production and sales documents with the parent item displaying first with gears listed below it. These components can be swapped out and replaced with other components, deleted from the BOM and sales document and the quantities can be updated.
