A purchased item that has been purchased by a business partner according to the Specifications of the Company and shall be used in unmodified form for the proper production of a superordinate article is required.
Component articles in SAP Business One
Component articles are articles that are used as components of a superordinate product in a Parts list (Bill of Materials, BOM) are kept. They form the basis for production, assembly and Material Requirements Planning in SAP Business One.
Use in the parts list
A bill of materials describes how an end product is manufactured. The component items are the subordinate elements that are required for production. Depending on the production structure, these can be
- Stock items (e.g. screws, raw materials)
- Parts list items (e.g. semi-finished products with their own parts list)
- Phantom article (non-stock-keeping structural units)
- Articles of the type labour (e.g. manual activities)
- resources (e.g. machines, personnel)
- Text objects (e.g. instructions)
Management in the article master
Each component article is maintained in the article master. Important tabs:
- Inventory dataWarehouse management, series/batch management
- Planning dataMRP-relevant fields such as procurement method, minimum quantity, lead time
- CharacteristicsClassifications for filtering
- Attachments and user fieldsIndividual additional information
Components for production BOMs are typically stock items. Items with sales or reference BOMs are not stock items.
Use in production orders
When a production order is created for a finished product, the defined component items are automatically included:
- They are drawn up during production.
- Your actual costs (material, labour, additional services) are recorded.
- the Cost allocation takes place via G/L account determinationdirectly in the parts list line.
Role in material requirements planning (MRP)
Of the Disposition assistant analyses requirements from orders and forecasts. In doing so:
- parts lists are exploded,
- the requirement for component parts is calculated,
- and procurement proposals are generated (e.g. purchase requisitions for purchased parts).
The MRP parameters defined in the article master control how procurement and planning take place.
Further contexts
- In Sales parts lists components are compiled during dispatch. Items of the type "Labour" are permitted here, but not resources.
- in the Project report the actual costs of the components are shown separately - differentiated according to material, resources and other services
