SAP DPP
Auto-generate a Digital Product Passport submodel from a supplier's PDF datasheet and push it into SAP DPP without manual data entry.
Audience: SAP integration architects + compliance officers running a Digital Product Passport rollout for the EU ESPR (Reg. 2024/1781).
Topology
- SAP DPP triggers a webhook (or scheduled job) when a new supplier datasheet lands in your DMS
- Your integration layer downloads the PDF and posts it to AAS Studio /api/v1/extract
- AAS Studio returns the structured DPP submodel with eCl@ss IRDIs already attached
- Your integration maps the result onto SAP DPP's expected aspect model and POSTs upstream
- Engineer cert + SHA-256 anchor become the audit-trail evidence for the ESPR market-surveillance authority

import { AasStudioClient } from '@aas-studio/sdk'
import { readFileSync } from 'node:fs'
const aas = new AasStudioClient({ apiKey: process.env.AAS_STUDIO_KEY! })
export async function ingestSupplierDatasheet(pdfPath: string, sapPartId: string) {
const pdf = readFileSync(pdfPath)
const { result, warnings } = await aas.extract({
file: pdf,
fileName: pdfPath.split('/').pop(),
idPrefix: `urn:acme:dpp:${sapPartId}`,
})
// Post to SAP DPP — the aspect-model mapping below is illustrative;
// adjust to your tenant's exact aspect schema.
const dppPayload = {
sapPartId,
aas: result,
warnings,
}
await fetch(process.env.SAP_DPP_URL!, {
method: 'POST',
headers: { 'Content-Type': 'application/json', Authorization: `Bearer ${process.env.SAP_TOKEN}` },

Common pitfalls
- SAP DPP's aspect model evolves with each delegated act — pin a schema version on your side and run a regression suite when SAP bumps it. AAS Studio's output is stable; your mapping layer is what changes.
- AAS Studio extractions over 80,000 chars of PDF text get truncated at the LLM step. For long supplier datasheets, the response's warnings array flags this — re-run with a smaller PDF or use multi-source extraction.
- Don't store the AAS Studio API key in SAP's tenant config — keep it in your integration layer's secret manager. The key gives full extraction quota access; rotate quarterly.
- For multi-language datasheets, AAS Studio extracts in the source language. SAP DPP usually wants German or English — add a translation pass between AAS Studio and SAP, or post both versions and let SAP pick.
