What Does It Do
One controlled engineering record Part identity + approved revision BOM + product structure + quantities Linked drawings + specifications Release history + supplier issue Linked records across the lifecycle

Connect Engineering Definition to Procurement and Supply

A connected lifecycle that begins with the engineering definition of a part and continues through BOM, product structure, purchase requisition, ERP purchase order visibility and supplier document delivery. The engineering layer stays in Wrench; enterprise procurement stays in ERP; and the thread between them is preserved by API integration and controlled transmittals.

  • Parts, BOMs and product structures
  • Controlled engineering documents and releases
  • Purchase requisitions and ERP purchase orders
  • Supplier transmittals and acknowledgements

What was engineered, what was purchased, who is supplying it, and the technical information issued — connected.

Key Capabilities

Key Capabilities

  • The structural foundation that connects engineering definition to component requirements.
Engineering-Driven PRs with Contingency Engineering requirement: 100 Contingency quantity: +5 Purchase requisition: 105 Controlled engineering information

Engineering-Driven PRs with Contingency

  • Engineers initiate purchase requisitions from the product structure.
  • Contingency quantities supplement the engineering requirement to account for defects, damage, wastage or project needs — the PR reflects true execution requirement.
PR → ERP · PO → Wrench Wrench PR → ERP procurement ERP PO → Wrench visibility Supplier · Quantity · Delivery date Controlled engineering information

PR → ERP · PO → Wrench

  • PRs transmitted to ERP via API for commercial procurement.
  • After PO release, header and line-item information returns to Wrench — PO number, supplier, part, quantity, delivery date — visible to engineering, PM and document control teams.
Supplier Technical Transmittals Drawing + Specification + Datasheet Controlled supplier transmittal Acknowledgement tracked Controlled engineering information

Supplier Technical Transmittals

  • Document controllers assemble the technical information associated with the part — drawings, specifications, supporting documents — and issue them to the supplier through controlled transmittals with acknowledgement tracking.
Audit Trail & Traceability Part release + BOM revision PR + PO + Supplier transmittal History connected to source records Controlled engineering information

Audit Trail & Traceability

  • Every stage — part release, ERP sync, BOM revision, PR issue, PO return, supplier transmittal, acknowledgement — captured in the audit trail.
  • Full traceability from engineering definition to supplier delivery, defensible under review.
Benefits

Benefits

Consolidation brings parts, BOMs, product structures and documents into one engineering environment. ERP integration eliminates duplicate manual entry. Controlled workflows govern approvals and releases. Transmittals link technical documents to purchased parts. The combined effect is a connected lifecycle that supports coordination between engineering, buyers, project management and document control.

Connected Digital Thread

Engineering definition flows to BOM, to product structure, to PR, to ERP PO, to supplier transmittal — one connected lifecycle instead of application-to-application handoffs with manual bridges in between.

No More Duplicate Entry to ERP

API integration transmits released parts to ERP for material master creation, and PRs to ERP for buying. The engineering information doesn't need to be re-keyed into the enterprise system by procurement coordinators.

Controlled Approvals & Audit Trail

Configurable workflows govern part status, revision, supporting documents, approval history and release — with structural audit trails. The engineering governance that was lost in email bridges is restored.

Procurement Visibility for Engineering

After PO release, engineering, PM and document-control teams see PO number, supplier, part, quantity and delivery date in Wrench — no need for full ERP seats or chasing procurement for status updates.

Contingency Captured Structurally

Engineers capture the gap between design count and execution reality as a structural field on the PR — defects, damage, wastage, project contingencies — not as a scribbled note on an email the buyer may miss.

Suppliers Get Coherent Delivery

The supplier receives the commercial PO from ERP and the technical documents from Wrench — controlled, versioned, acknowledged — not a PO from procurement and a stream of email drawings from engineering.

Does Wrench replace ERP?

No. Wrench provides the engineering information layer; ERP remains the enterprise transaction layer. The two systems operate in parallel, connected by API integration. Wrench holds parts, BOMs, product structures, engineering documents and purchase requisitions. ERP holds material masters, commercial procurement, purchase orders and financials. The customer who implemented this model kept ERP for enterprise procurement throughout — Wrench added the engineering layer that was previously spread across PLM, Documentum and manual bridges.

What exactly flows between Wrench and ERP via API?

Two primary integration paths:

  • Wrench → ERP · Released Parts: Once an engineering workflow releases a part, it is transmitted to ERP via API to support material master creation using the MM01 process — including Basic 1 and Basic 2 information.
  • Wrench → ERP · Purchase Requisitions: PRs created in Wrench (from the product structure, with contingency applied) are transmitted to ERP for commercial procurement.
  • ERP → Wrench · PO Information: After a PO is released in ERP, header and line-item data return to Wrench — PO number, supplier, part, quantity, requested delivery date, line items and related procurement requirements.

Buyers continue to perform commercial procurement in ERP — supplier selection, negotiation, PO issuance — while engineering and document-control teams see the resulting PO information in Wrench.

How does the contingency quantity mechanism work?

Engineers include contingency quantities on the PR to account for anticipated material defects, damage, wastage or project execution needs. The contingency is a structural field on the PR alongside the engineering quantity — not a note in an attachment or a verbal instruction to procurement. In the typical example, an engineering requirement of 100 units with a contingency of 5 units produces a procurement requirement of 105 units. ERP buys the full 105, the engineering design remains the authoritative 100, and the gap is captured and visible — not lost in translation. This replaces the common pattern where contingency gets added informally and procurement, engineering and project control teams end up with three different numbers for the same part.

What is a "part record" in Wrench, and what does it hold?

A part record is the single engineering reference point for an item, with configurable attributes across:

  • Engineering: design identifier, revision, specifications
  • Material: grade, finish, physical properties
  • Manufacturer & Supplier: approved sources, part numbers
  • Quality: inspection & compliance requirements
  • Procurement: commercial attributes for sourcing

Each part also acts as the reference point for its supporting documents — drawings, specifications, technical datasheets, supplier documentation, quality documents, certificates, MSDS/SDS, inspection and compliance records. The part definition and all its supporting information live together as one controlled engineering record.

How is the engineering release controlled?

Each part moves through a configurable workflow that routes it through engineering review, approval and release. The workflow governs part status, revision, supporting documents, approval history, release status and authorized use. Only the approved and released engineering definition moves downstream — meaning only a controlled, formally governed version is used for ERP material master creation and for procurement. This is the structural control that prevents in-progress or unreleased engineering from accidentally flowing into enterprise systems or supplier packages.

How does supplier documentation work alongside the ERP PO?

Suppliers receive two inputs that work as one coherent delivery: the commercial Purchase Order from ERP, and the controlled technical documents from Wrench. Document controllers in Wrench assemble the technical information associated with the ordered part — drawings, specifications, datasheets, MSDS/SDS, quality certificates, inspection & compliance records — and issue them to the supplier through controlled transmittals with acknowledgement tracking. ERP handles the commercial transaction; Wrench handles the technical content; the supplier doesn't have to assemble the real picture from fragments across email and attachments.

Can this model work with ERPs other than ERP?

Yes. The reference implementation described here uses ERP, but Wrench's API integration pattern is ERP-agnostic. The same model — released parts flowing to material master, PRs flowing for commercial procurement, PO information returning for engineering visibility — can integrate with Oracle, Microsoft Dynamics, Infor, or other enterprise ERP systems. The core principle holds whichever ERP is in place: Wrench provides the engineering information layer; the ERP provides the enterprise transaction layer; the API preserves the thread.

How are BOM changes and revisions handled across the thread?

BOM revisions and part revisions each move through their own controlled workflow, with the audit trail preserving the change history, approval chain and release status. Because the part is the reference point for its documents, any revised drawing or specification is linked back to the part revision that triggered it. When a BOM revision affects already-purchased parts, the PO visibility in Wrench and the transmittal history provide the context required for decisions on supplier re-issue, change notification or impact assessment — rather than a scramble to reconstruct what was issued, to whom, and based on which revision.
