A multi-site industrial manufacturer challenged SAP's GROW engine measurement, established the contracted definition was inconsistent with the audit output, and settled at seventy-eight per cent below the opening number.
Every result on this site is anonymised at the client's request. Specific figures are real and verifiable through a confidentiality-protected reference call arranged on request.
The client is a multi-site industrial manufacturer with operations across the United States, Mexico, and Brazil. The company had moved onto GROW with SAP eighteen months earlier in a phased migration from a legacy on-premise ERP, with the GROW contract including four engine entitlements covering Process Orchestration, Quality Management, Production Planning extensions, and a custom-bundled materials handling engine.
The trigger was a formal engine measurement request issued under the audit-rights clause of the GROW contract. SAP's audit team requested measurement output across all four engines, supported by configuration data and transaction extracts covering the prior twelve months. The request was framed as a standard cyclical measurement rather than a triggered audit.
The measurement output, prepared by the manufacturer's internal team and supplied to SAP, was followed three weeks later by a claim notice asserting six point three million dollars in shortfall across three of the four engines. The notice cited the measurement output as definitive and proposed a settlement-and-uplift package linked to a forward contract amendment.
The CFO authorised outside engagement before any further data was supplied and before the proposed settlement package was discussed substantively with the SAP account team.
SAP's claim was built on a direct application of the measurement output as supplied. The output had been generated using the standard SAP measurement reports without any pre-submission validation against the contracted definitions. The audit team had accepted the manufacturer's own numbers and converted them into a chargeable position.
The six point three million broke into three lines: two point eight million on the Process Orchestration engine; two point one million on the Quality Management engine; and one point four million on the materials handling engine. The Production Planning engine measurement was within the contracted ceiling and was not part of the claim.
The settlement-and-uplift framing meant that SAP was offering to discount the back-claim if the manufacturer agreed to a forward expansion of two of the engines plus a renewed indirect-access baseline. That structure coupled the engine measurement to a broader contract conversation, which the procurement team treated as a leverage signal.
The manufacturer's internal measurement had used SAP's default measurement reports without contract-aware filtering. We rebuilt each of the three challenged engine measurements against the contract definition. The Process Orchestration measurement reduced by sixty-four per cent once internal system traffic was excluded per the contract definition.
The Quality Management engine measurement had counted historical issue-management records that had been migrated from the legacy ERP and were not subject to ongoing chargeable use. We re-anchored the measurement to the contracted in-period scope, removing approximately seventy-one per cent of the QM line.
The materials handling engine had been measured against a metric that did not match the bundle annex. The bundle annex specified a sites-served metric; the measurement had been performed on a handling-units metric. Re-measurement against the contracted metric reduced the line by approximately fifty-five per cent.
We decoupled the back-measurement matter from the forward contract conversation in writing, removing the leverage the coupled offer had created. The forward expansion conversation was then re-opened on its own commercial merits and resulted in a smaller, better-priced amendment.
Settlement closed at one point four million dollars, against an opening claim of six point three. The reduction was approximately seventy-eight per cent. The forward contract amendment was renegotiated separately on standard commercial terms.
Four contract changes were written into the settlement. Each of the three challenged engine measurement definitions was specified in a numbered annex with worked examples. A pre-submission validation protocol was added requiring the manufacturer to validate the measurement output against the contract definitions before submission to SAP. A non-coupling clause was added preventing the linking of back-measurement matters to forward amendments. And the audit-rights notice period was extended to ninety days.
Total elapsed time from the original claim notice to executed settlement was thirteen weeks. The forward engine expansion proceeded on a smaller, decoupled basis aligned to the manufacturer's actual capacity plans rather than SAP's proposed scope.

The numbers SAP cited were ones we had given them ourselves. The fix was not to argue the math but to fix the inputs the math had been built on.
