SAP Manufacturing Cost Estimate with Claude & Gmail Automation

SAP Manufacturing Cost Estimates—Automatically Calculated with Claude and Sent via Gmail

Get faster, more consistent manufacturing quotes: this n8n workflow receives a part request through a webhook, pulls SAP material/BOM/purchase data plus live commodity prices, uses Anthropic (Claude) to compute costs and risk, then creates the sales quotation in SAP and emails it via Gmail—returning the quote JSON to your system.

What this workflow does

• Receives requests via a POST webhook containing partNumber, quantity, and deliveryDate.
• Loads configuration such as the SAP OData base URL/credentials, commodity price API URL, overhead and margin rates, and the sales team email address.
• Fetches SAP data: material stock, bill of materials (BOM), and purchase information records.
• Retrieves live market inputs using current commodity spot prices from metals.live.
• Aggregates data into a single dataset for analysis.
• Uses Claude to calculate material costs, estimate machining costs, apply overhead and margin for final pricing, and assess quote risk with a confidence range.
• Generates structured results as a quote JSON including the cost breakdown, pricing, and risk details.
• Executes commercial steps: creates a sales quotation in SAP, emails the quote details to the sales team via Gmail, and returns the quote JSON as the webhook response.

Use cases

• Automate quote turnaround for ERP-driven manufacturing requests from internal apps or customer portals.
• Keep sales pricing aligned with real-time commodity spot prices and documented SAP BOM/purchase context.
• Provide sales teams with risk-aware quotations (confidence range + risk details) directly in email.
