+# ServiceNow Approval Matrix Generator  
+**A Dynamic, Data-Driven Approval Workflow Engine for ServiceNow**
+
+---
+
+## Overview
+
+The **Approval Matrix Generator** is a configurable engine that automates approval generation in ServiceNow based on business rules —  
+without hard-coding approvers or creating dozens of Flow Designer flows.  
+
+By maintaining a simple **Approval Matrix table**, you can define which user or role should approve a request dynamically (e.g., based on department and amount).  
+This approach provides scalability, maintainability, and full visibility across all approval logic.
+
+---
+
+## Key Highlights
+
+✅ 100% native ServiceNow solution (no plugins)  
+✅ Centralized approval logic in a single configuration table  
+✅ Works for ITSM, HRSD, Finance, or Procurement workflows  
+✅ Supports multi-level approvals (Manager → Director → CFO)  
+✅ Can run via **Business Rule** 
+
+---
+
+## Use Case
+
+An organization wants dynamic approval routing for procurement or HR requests based on:
+- Department (IT, HR, Finance)
+- Request amount (₹0–₹10,000, etc.)
+- Approval role (Manager, Director, VP)
+
+Instead of building multiple flows, the Approval Matrix defines all rules in a single table.  
+When a new request is submitted, the script automatically finds and assigns the correct approvers.
+
+---
+
+## Step 1 — Create Table `u_approval_matrix`
+
+| Field | Type | Description |
+|--------|------|-------------|
+| **u_department** | Reference (sys_user_group) | Department owning the rule |
+| **u_min_amount** | Decimal | Minimum amount for range |
+| **u_max_amount** | Decimal | Maximum amount for range |
+| **u_role** | Choice | Role type – Manager / Director / VP |
+| **u_approver** | Reference (sys_user) | Direct approver (optional) |
+
+This table drives all the logic.  
+Example data:
+
+| Department | Min | Max | Role | Approver |
+|-------------|-----|-----|------|-----------|
+| IT | 0 | 5000 | Manager | *(blank)* |
+| IT | 5000 | 10000 | Director | *(blank)* |
+| Finance | 0 | 10000 | *(blank)* | John CFO |

+
+## ⚙️ Step 2 — Business Rule Script
+
+**Table:** `sc_request` (or your custom table)  
+**When:** After Insert  
+**Condition:** Approval required
+
+## Example Input (Request Record)
+| Field         | Value             |
+| ------------- | ----------------- |
+| Requested For | Ravi Gaurav       |
+| Department    | IT                |
+| Amount        | 8000              |
+| Category      | Hardware Purchase |
+
+## Example Output
+| Field                | Value                                     |
+| -------------------- | ----------------------------------------- |
+| Matched Rule         | IT, 5000–10000, Role = Director           |
+| Approver Found       | Ravi’s Director (from `u_director` field) |
+| Approval State       | Requested                                 |
+| sysapproval_approver | Created Automatically                     |
