How a Dynamic BOM Works
A dynamic BOM begins with a configurable product model and rules that define how selected options affect its structure. As a user specifies dimensions, materials, capacity, accessories, or other attributes, the configurator evaluates the selections and determines which components and quantities apply. The resulting BOM may include standard components, optional items, or subassemblies required by the selected configuration.
For example, a manufacturer selling industrial pumps might offer three motor sizes and two seal materials. The configuration rules can select the appropriate motor and seal based on the customer's choices while retaining common components such as the housing and mounting hardware. The resulting structure gives production planners a product-specific view of the required materials.
The process should also preserve the relationship between the configured product, its part identifier, and the relevant manufacturing records. Depending on the implementation, the output may select an existing structure, apply configured component rules, or create or update records through supported functionality.
Core Components of a Dynamic BOM
Several elements work together to produce a usable, configuration-specific material structure:
- Product attributes: Capture the dimensions, performance specifications, materials, and options selected for the order.
- Configuration rules: Determine which components are included, excluded, or adjusted for each permitted combination.
- Component and quantity definitions: Specify the parts and quantities needed for the selected design.
- Part and engineering records: Connect the configuration to valid item data, revisions, and approved manufacturing specifications.
- Manufacturing integration: Makes the resulting material requirements available to supported planning, production, and inventory workflows.
A standard Bill Of Materials Bom defines the components needed for a product, while a dynamic BOM allows that structure to respond to configuration choices. The governing rules should establish which options affect component selection, quantity, revision, or routing so that the generated structure matches the intended design.
Manufacturing and Costing Use Cases
Dynamic BOMs are particularly useful for make-to-order and configure-to-order manufacturers. They allow product variations to share common components while retaining the specific materials required for each order. This supports more accurate material planning, purchasing, production scheduling, and inventory allocation.
Consider a configured machine requiring a base assembly costing $1,200, a motor costing $450, and an optional control unit costing $180. If the selected configuration includes the control unit, the listed component cost is $1,200 + $450 + $180 = $1,830, assuming one of each component and excluding labor, overhead, scrap, and other costs. If the control unit is not selected, the component total is $1,650. These figures illustrate how configuration choices can affect the expected material cost.
Finance and operations teams can use the resulting component structure alongside item costs and inventory transactions to understand material consumption and product margins. Actual accounting results depend on the organization's costing method, transaction timing, and ERP setup.
Rules, Validation, and Maintenance
Effective dynamic BOM design starts with clear product rules and shared ownership across engineering, manufacturing, and purchasing. Teams should test representative configurations before releasing rules for production and confirm that each output contains the intended components, quantities, and revisions.
- Validate required and mutually exclusive options so that each configuration produces an approved material structure.
- Check quantity calculations for options that require multiple components or depend on product dimensions.
- Align BOM changes with engineering revisions and the company's part-numbering policies.
- Confirm that configured materials flow correctly into purchasing, inventory, production, and costing processes.
- Review rule changes with relevant teams and retain traceable records of approved configuration behavior.
When the product structure depends on changing engineering specifications, teams should define when an existing BOM can be reused and when a distinct revision or structure is required. This keeps order-specific manufacturing information aligned with the design that was approved.
ERP Integration and Finance Workflows
Within epicor, a dynamic BOM can connect product configuration with supported manufacturing and ERP workflows. Epicor ERP provides a broader environment for managing operational records, while Epicor Integration Finance describes the connection between ERP data and finance processes. Accurate component and quantity information helps operations and finance teams reconcile material movements with the appropriate production and inventory records.
The Hyperbots Platform supports company-specific configuration across ERP integrations, workflows, roles, and general ledger structures. Its Process Specific Capabilities tailor AI automation to defined business workflows, and Ready to Deploy Capabilities provide pre-trained agents and ERP connectors for supported finance tasks. Self Learning Capabilities can use human actions to refine supported workflows, while Human in the Loop processes provide review and approval where required.
These capabilities can complement manufacturing data by supporting finance activities around transactions generated by operational systems. For instance, accurate inventory and receipt records can help finance teams identify goods received but not yet invoiced. A structured Transform Your Accruals Process—Get Started with Hyperbots approach can support accrual discovery, estimation, booking, and month-end expense recognition using relevant transaction evidence.
When customers pay invoices related to manufactured orders, separate accounts receivable workflows may match remittances to open invoices and identify unapplied cash before posting receipts.

Summary
Epicor Configurator Dynamic BOM connects product selections with the components and quantities required to manufacture a configured item. Its value comes from well-defined rules, validated product data, controlled engineering revisions, and reliable integration with manufacturing and ERP workflows. When maintained consistently, a dynamic BOM supports material planning, purchasing accuracy, production coordination, and better visibility into product costs.
