Automated Material Request Approval and Stock Management
detail.loadingPreview
Streamline your material request process from submission to stock deduction. This workflow automates logging requests in Google Sheets, generating unique approval links, and updating inventory levels upon approval, ensuring efficient and error-free material issuance.
About This Workflow
This n8n workflow provides a robust solution for managing material requests and inventory updates. It starts by standardizing incoming material requests, automatically generating a unique submission ID and a dynamic approval link. These requests, along with a 'Pending' status, are then meticulously logged into a Google Sheet. Once an approver interacts with the generated link, a dedicated webhook triggers the second phase, where the approved quantity is processed. The workflow then intelligently updates your stock levels, safeguarding against negative inventory with built-in error handling. This automation reduces manual effort, accelerates approvals, and maintains accurate inventory records.
Key Features
- Automated Request Logging: Automatically append new material requests, including critical details and status, to your Google Sheets.
- Dynamic Approval Links: Generate unique, webhook-driven approval links for each request, simplifying the approval process.
- Webhook-Driven Approval: Enable approvers to process requests with a single click, triggering subsequent actions instantly.
- Real-time Stock Deduction: Update inventory levels by deducting approved quantities from your current stock, preventing manual errors.
- Inventory Safety Checks: Implement logic to prevent stock from dropping below zero, ensuring accurate inventory management.
- Customizable Data Standardization: Easily map and transform incoming request data to fit your specific record-keeping needs.
How To Use
- Configure Your Trigger: Set up an initial trigger (e.g., a form submission, another n8n webhook, or an external system) to feed raw material request data into the workflow.
- Customize 'Standardize Data': Map your incoming data fields (like 'Product ID', 'Quantity Requested', 'Requested By') to the corresponding standardized output fields. Ensure the 'Approval Link' value points to the 'Get Approvals' webhook URL.
- Connect 'Append Material Request': Select your Google Spreadsheet ('Plumbee Raw Material Delivery (Responses)' in the example) and the specific sheet ('Materials Issued') where you want to log material requests. Verify column mappings.
- Set Up 'Get Approvals' Webhook: Note the unique URL generated by this node. This URL will be embedded in the 'Approval Link' in the 'Standardize Data' node and sent to approvers.
- Refine 'Update Stock' Logic: Customize the JavaScript code in the 'Update Stock' node. You'll need to fetch the 'Current Stock' (e.g., from another Google Sheet or database) and retrieve the 'Approved Quantity' (which typically comes from an intermediate node, e.g., 'Verify Approval Data' as referenced, that parses the approval webhook payload).
