Notification Queries

Hello,

I have created a doctype called “Test”, and there is a field called “Subscription Renewal Date”.

I’m trying to set a notification for it. I was able to set notification on 2 Days Before the subscription renewal date.

So, I want to know what would be the condition if i want to get notification on the same day as subscription renewal date. Also what should I select in the field “Send Alert On”?

Please help.

Thanks & Regards,
Sujay
