you can use before update business rule and check and abort the update.
Condition: Category Changes to Service
Script:
(function executeRule(current, previous /*null when async*/ ) {
// Add your code here
var gr = new GlideRecord("incident");
gr.addQuery("rfc", current.sys_id);
gr.query();
if (!gr.hasNext()) {
gs.addErrorMessage('Please add data in related list');
current.setAbortAction(true);
}
})(current, previous);
