For example, if you’re managing two transport aircraft variants with distinct cargo setups, you can quickly identify unique and shared components. This ensures any changes to one variant won’t inadvertently affect the other.
This system also includes an intuitive change management process. Proposed adjustments trigger a structured workflow for creating change records, submitting requests for approval, and logging all activities for traceability. Detailed change logs show who made the request, what changes were made, and how those changes affect other assemblies. This helps you comply with industry standards like AS9100, providing an auditable trail to meet regulatory needs. Once approved, updates automatically cascade through nested BOM levels, minimizing manual errors.
S/4HANA integrates with SAP PLM and third-party platforms to sync engineering data like CAD files and 3D models. This means your manufacturing processes immediately reflect any design changes in real-time. Additionally, S/4HANA offers impact analysis capabilities, which make it easier to understand how changes at one level of the BOM will ripple through production.
S/4HANA is an enterprise-level system, with hosted subscription costs starting at $20,000 per month and on-premise perpetual licenses ranging from $200,000 to over $2 million.

What Is Engineer-to-Order Software?
ETO software streamlines the design, engineering, and fabrication of unique, client-specific products. As a type of discrete manufacturing software, it supports assembling individually identifiable and disassemblable items.
These systems emphasize customer participation throughout the project and incorporate engineering tasks into lead time calculations, providing a more accurate timeline for buyers. Engineer-to-order platforms enable selling product concepts instead of predefined models, so the software must support custom-build processes in both the ideation and development phases.
How ETO differs from other manufacturing types:
- Make to Order (MTO): Produces items based on client orders with limited customizations, like different finishes, dimensions, or materials, often using product configuration tools.
- Make to Stock (MTS): Focuses on producing high-volume items for immediate sale, emphasizing automated inventory replenishment and demand forecasting.
Process Flow
- The customer submits a sales order, including quoted costs and anticipated delivery dates.
- The project team selects employees with specific skill sets, schedules production blocks, and determines raw materials needed for the job.
- The company creates a BOM detailing all components needed to complete the order, fulfilled by current inventory or through procurement.
- The team researches, ideates, and submits the custom design for client approval.
- MRP generates a finalized list of material requirements, allocates labor and machinery, and schedules purchasing to meet production timelines.
- After completing the planning phase, the company manufactures and assembles the final product.
