Hello @Mansi roy
I am not sure how your impacted services are calculated. But if it just relies on the services field - you can make it mandatory using client script, BR or anything.
Else, you can use below 👇 BR
if (!new GlideRecord('task_ci').addQuery('task', current.sys_id).hasNext()) {
gs.addErrorMessage('At least one Impacted Service must be added before proceeding.');
current.setAbortAction(true);
}
In the condition field add suitable conditions like state changes to implement it asses or review whatever you prefer, on update business rule.
Kindly mark my answer as helpful and accept solution if it helped you in anyway. This will help me be recognized for the efforts and also move this questions from unsolved to solved bucket.
