+This business rule is designed for ServiceNow to prevent a parent incident from being closed or resolved while it still has active child incidents.
+If a user attempts to set the parent incident's state to "Resolved," "Closed," or "Cancelled," the rule will query for any related child incidents that are still open. 
+If open children are found, the update will be aborted, and an error message will be displayed to the user.
+
+Navigate to System Definition > Business Rules in the ServiceNow filter navigator.
+Click New.
+Fill out the form with the following details:
+Name: Prevent Parent Closure with Open Children
+Table: Incident [incident]
+Advanced: true
+When: before
+Update: Check this box.
+In the When to run tab, set the Condition field:
+current.state.changesTo(7) || current.state.changesTo(6) || current.state.changesTo(8)  //The state values are: 6 (Resolved), 7 (Closed), 8 (Cancelled).
+Note: The state values (6, 7, 8) may vary based on your instance configuration.
+In the Advanced tab, paste the provided script into the Script field.
