+📘 README — Auto Update Resolution SLA on Related Tasks
+Business Rule Details
+
+Name: Auto Update Resolution SLA Reference
+Table: task_sla
+Execution: After Insert
+Filter Condition: SLA Definition target must be Resolution
+Condition: Runs only when the associated task is an Incident or a Catalog Task
+(current.task.sys_class_name == 'incident' || current.task.sys_class_name == 'sc_task')
+
+Purpose
+
+This Business Rule is designed to automatically update the related Incident and Task records with the Resolution SLA reference when a new Task SLA record is created.
+It helps provide direct visibility of SLA details from the Incident or Task form without navigating to the task_sla table.
+
+How It Works
+
+A new Resolution SLA is created for a task.
+
+This rule triggers after the Task SLA record is inserted.
+
+It checks if the related task is an Incident or a Catalog Task.
+
+It updates the custom SLA reference fields on both the Incident and the Task.
+
+Prerequisites
+
+You must create the following fields before using this rule:
+
+Field: u_resolution_sla (On Incident table)
+Type: Reference to task_sla
+
+Field: u_task_resolution_sla (On Task table)
+Type: Reference to task_sla
+
+Testing Steps
+
+• Create a new Incident and associate a Resolution SLA with it.
+• Allow the SLA to start (so it creates a task_sla entry).
+• Open the Incident and related Task.
+• You should see the Resolution SLA reference auto-populated in both.
+
+Script Used
+(function executeRule(current, previous /*null when async*/ ) {
+
+    var inc = new GlideRecord('incident');
+    inc.get(current.task);
+
+    inc.u_resolution_sla = current.sys_id;
+    inc.update();
+	
+    var tsk = new GlideRecord('task');
+    tsk.get(current.task);
+
+    tsk.u_task_resolution_sla = current.sys_id;
+    tsk.update();
+
+})(current, previous);
+
+Result
+
+This automation ensures the SLA is visible and reportable on both Incident and Task records with no manual updates.
+It improves SLA tracking, reporting, and overall usability.
