Procore × SAP integration.

A custom-built sync between Procore and SAP S/4HANA or ECC. Projects, WBS elements, commitments, vendor invoices, and cost objects move bidirectionallyagainst the Procore REST API and SAP via OData through SAP Integration Suite, with BAPI fallbacks where OData doesn’t cover the object. Authorization-aware, change-document-clean, designed to sit inside an enterprise SAP transformation program.

01. What syncs, what doesn’t

WBS-aware. PS-module-clean.

The object map below assumes SAP PS (Project System) with a standard WBS hierarchy. For customers running CO with internal orders instead of PS, the mapping shifts to internal orders and cost centers. Direction is configurable per object during the audit.

What stays in SAP:GL postings, consolidation, intercompany, period-end closing, tax determination, and all CO settlement runs. The integration provides clean inputs; SAP’s standard postings and settlement runs do the math.
02. The boundary problem this solves

Enterprise SAP doesn’t flex. Procore doesn’t know SAP’s rules.

Enterprise GCs and industrial owners running SAP have spent years configuring it — release strategies, validation rules, authorization profiles, custom workflow per division. SAP is not going to bend to a Procore connector.Anything writing into SAP has to respect the workflow, pass the validation, and use the right authorization. Generic connectors either fail those checks or get granted excessive authorization that the security team can’t justify in the next audit.

The custom integration sits inside SAP Integration Suite as an iFlow with the right authorization profile and the right BAPI / OData calls for each object. The Procore-side service runs in your cloud and talks to the iFlow over an authenticated channel. The SAP basis team owns the iFlow side; we own the Procore side and the transformation. The split mirrors how every other enterprise integration into SAP is run, which is why the security team approves it without rewriting it.

This is the integration we get asked about by enterprise GCs running multi-region SAP, asset owners with a Central Finance instance, and industrial coatings operators whose plant maintenance and project execution data both live in SAP.

Procore × SAP isn’t a connector problem. It’s a workflow-respecting interface design problem with two sets of stakeholders that have to sign the same spec.

03. How we build it

OData where it exists. BAPI where it doesn’t.

The Procore side runs on the Procore REST API v1.0 with OAuth 2.0 and webhook subscriptions. The SAP side runs through SAP Integration Suite as one or more iFlows, with OData calls into S/4HANA (or PI/PO into ECC) for read traffic and BAPI calls for writes where OData doesn’t cover the object. The service user’s authorization profile is scoped to the minimum needed — no SAP_ALL, no broad write access.

The transformation layer lives in your cloud as a thin Node service that holds the field-mapping config and the WBS-routing rules, and talks to the iFlow over an authenticated channel. All writes generate SAP change documents so the audit trail is preserved in the standard SAP audit log. Exception cases land in a dual-side queue — a Procore-side admin UI for the project team, a CPI alert for the basis team — so both sides see what failed. Code in your repo, infrastructure in your cloud, SAP credentials in your secret store.

The 14-Day Audit

Fixed fee · 14 days

We map the Procore × SAP surface end-to-end with your SAP basis team. WBS structure, authorization profile, iFlow boundaries, what stays manual. Output: a written interface specification ready for SAP-side review. More on the audit →

The Build Engagement

Scoped quote · 12–20 weeks

The implementation. iFlow setup, the Procore-side transformation, the WBS-mapping admin UI, the dual-side exception queue. Tested in your SAP quality system before touching production.

SAP gets quarterly enhancement packages. Procore ships API updates. We retain a fractional engineering presence and coordinate with your basis team on version changes. Capped hours.

05. Frequently asked

Procurement-stage questions we get on this one.

Does Procore have a native SAP connector?

Procore offers an SAP connector as part of its ERP Integrations program, with deployment partners covering S/4HANA and ECC. The connector handles a baseline subset of objects. Enterprise GCs and industrial owners typically need a custom layer to handle their specific WBS structure, document-flow handling, and the workflow rules already encoded in SAP. We build that layer against the Procore REST API and SAP via OData services exposed through SAP Integration Suite (or, where required, direct BAPI calls).

S/4HANA or ECC?

We've shipped both. S/4HANA exposes a richer OData surface and pairs with SAP Integration Suite (formerly CPI / SCP Integration). ECC requires more BAPI work and typically PI/PO or a third-party middleware on the SAP side. The integration patterns are different but the Procore side is the same. The audit covers your specific SAP landscape — including whether you have a Central Finance instance in front of the operational ECC system.

How do you handle WBS elements and the project hierarchy?

SAP's Project System (PS) module uses WBS elements with a hierarchical structure that Procore's flatter project model doesn't represent natively. We map Procore projects to a WBS branch with the level configurable per customer. Procore cost codes map to WBS network activities or to internal orders depending on how your PS module is configured. The mapping table is editable by the SAP basis team, not just by us.

What about authorization checks and SAP roles?

Every write into SAP goes through a service user with the minimum authorization profile needed for the objects we touch. We don't share that user across customers and we don't ask for elevated SAP_ALL access. The Procore-side OAuth token is scoped to the company-level installation per Procore's published guidance. Audit logs are preserved in SAP's standard change documents; the integration doesn't bypass them.

Is this scope viable inside an existing SAP transformation program?

Yes, and that's how most of these get scoped. Procore × SAP integrations rarely happen in isolation — they typically sit inside a larger digital-construction or S/4HANA migration program with multiple stakeholders. We work alongside your SI partner or in-house SAP team, take ownership of the Procore side and the integration middleware, and align our delivery cadence with the broader program plan. The audit produces a written interface specification that your SAP team can review before code lands.
