+# CI Deduplication Task Generator
+
+This script rechecks the cmdb_ci_hardware table for duplicates by serial number and creates a De-Duplication Task if needed (for records that didn't run through the IRE).
+
+### How It Works
+
+1. Finds all serial numbers that are used on more than one hardware CI.
+
+2. For each group of duplicates, it checks if any of the CIs are already part of an open de-duplication task.
+
+3. If no open task exists, it creates a new one linking all CIs in the group.
+
+4. Logs a summary of actions taken (tasks created, groups skipped).
+
+### Dependencies
+
+This script requires the `global.CMDBDuplicateTaskUtils` Script Include to be active in your instance.
+
+### Configuration & Use
+
+This script is meant to be run as a **Scheduled Job** or as a **Background Script**.
+
+Before you run it, you must set the target table.
+
+```
+// Change this line in the script!
+var ciTable = "cmdb_ci_hardware" 
+
+
+```
+
+Change `"cmdb_ci_hardware"` to the table you want to run the script against.
+
+### Example Log Output
+
+```
+Starting check for duplicate CIs by serial number...
+==> Successfully created task RITM0010123 for Serial Number "VMW-50-81-7A-C9-23-44".
+--> Skipping Serial Number "SGH814X025". It is already part of an open task.
+--- Re-check Complete ---
+Total Duplicate Groups Found: 2
+New Remediation Tasks Created: 1
+Groups Skipped (Already in an open task): 1
+--------------------------
+
+
+```
