+📘 README — Auto Assignment by Application Group Variable
+ServiceNow Business Rule — sc_req_item
+✅ Purpose
+
+This Business Rule automatically sets the Assignment Group on a Requested Item (RITM) based on the user’s selection in a catalog variable. It also updates the mapped variable value in the sc_item_option_mtom table to ensure data consistency across catalog records.
+
+🔧 Where This Script Runs
+Item	Details
+Table	sc_req_item
+When	Before Insert / Before Update
+Script Type	Business Rule
+Execution Scope	Server-side
+📌 Prerequisites
+
+For this script to operate correctly:
+
+1️⃣ Catalog Variable exists on the item:
+
+Name → dummy_app_group
+
+Type → Select Box
+
+Possible Values → AppGroup A, AppGroup B, AppGroup C, etc.
+
+2️⃣ Assignment Group sys_ids should be updated to real sys_ids in Production.
+
+3️⃣ The variable that stores reference to the group must be mapped in M2M table:
+
+Name → dummy_group_variable
+
+Type → Reference (sys_user_group)
+
+4️⃣ Assignment Group field must be visible and editable on RITM.
+
+🚀 What the Script Does
+
+✔ Reads catalog variable value selected by requester
+✔ Matches the value and determines corresponding Assignment Group
+✔ Updates RITM field assignment_group
+✔ Updates dummy_group_variable in sc_item_option_mtom table
+✔ Displays info/error messages for debugging and validation
+
+🧩 Example Mapping Used in This Script
+Catalog Variable Value	Assignment Group (Dummy sys_id)
+AppGroup A	11111111111111111111111111111111
+AppGroup B	22222222222222222222222222222222
+AppGroup C	33333333333333333333333333333333
+
+Replace with actual assignment group sys_ids before deployment.
+
+✅ Benefits
+Feature	Advantage
+Automated Group Assignment	Eliminates manual errors & delays
+Consistency in Catalog Variables	Accurate reporting and auditing
+Debug-Friendly Messaging	Quick validation during testing
+🛠️ Deployment Notes
+
+Disable info messages (gs.addInfoMessage) after successful testing
+
+Maintain updates when catalog variable choices expand
+
+Avoid hard-coding by considering future enhancement → mapping object / system properties
