+# 🔄 ServiceNow Fix Script: Normalize "prod" Environment Using GlideFilter
+
+## 📌 Problem Statement
+
+In many ServiceNow environments, custom fields like `u_environment` on tables such as `change_request` often contain inconsistent variants of the same logical value, for example:
+
+- `prod`
+- `PROD`
+- `Prod`
+- `PrOd`
+- `pRoD`
+
+These inconsistencies cause:
+- Confusion in reports
+- Broken automation rules
+- Poor data hygiene
+
+This script identifies and normalizes all case-variant values of `"prod"` to a consistent format: `"Prod"`.
+
+---
+
+## 🚀 Solution: Fix Script Using GlideFilter
+
+We use **`GlideFilter`** with **case-sensitive matching** to cleanly and securely identify inconsistent values. This avoids multiple `if` conditions or regular expressions.
+
+---
+
+## ✅ Practical Example
+
+Instead of writing custom logic like this:
+
+```javascript
+var env = gr.u_environment.toString().toLowerCase();
+if (env === 'prod' || env === 'prod ' || env === 'PROD' || env === 'PrOd') {
+    // Normalize
+}
+```
+
+You simply write:
+```javascript
+var filter = new GlideFilter('u_environment=prod', 'envNormalize');
+filter.setCaseSensitive(false);
+if (filter.match(gr, true)) {
+    // Normalize
+}
+```
+
+✅ Cleaner
+✅ ACL-aware
+✅ Easier to maintain
+✅ Consistent with UI filters
+
+## GlideFilter Utility
+
+🧠 **Why Use GlideFilter?**
+
+| Feature                         | GlideFilter | Regex / If |
+|---------------------------------|-------------|------------|
+| Security-aware (ACLs)          | ✅ Yes      | ❌ No      |
+| Case sensitivity toggle         | ✅ Yes      | ⚠️ Manual  |
+| UI-like filter syntax           | ✅ Yes      | ❌ No      |
+| Easy to read                    | ✅ Yes      | ❌ No      |
+| Scalable & reusable             | ✅ Yes      | ❌ No      |
+| Compound condition support       | ✅ Yes      | ⚠️ Complex to build |
+
+💡 **Use Cases**
+- Normalizing environment values (prod, dev, test)
+- Standardizing priority or category values
+- Filtering GlideRecords based on secure, compound conditions
+- Any script where you're mimicking UI filter logic in code
+
+🛠️ **How to Use**
+1. Go to **System Definition** → **Scripts - Background**.
+2. Paste the script above.
+3. Click **Run Script**.
+4. Check **System Logs** (gs.info) to verify updates.
