Business Event -- need Task and Email assistance

@swartzfeger The task side is close. The catch is the Value column on Task Settings: it wants a formula, not @today. Another user had @today and @today+30 there and the task came out with no dates. Keep From Schema cleared on these rows and change the values to:

Start Date: =Today()
Due Date: =DateAdd(Today(),'d',7)
Remind At: =DateAdd(Today(),'d',7)

Your Reminder row is already right. nhatnghetinh showed the fix working here: https://community.acumatica.com/everything-else-119/setting-dynamic-due-start-dates-for-tasks-26226

The email is the harder half. A business event has no delay setting, so its email subscriber goes out as soon as the record-change event fires. The schedule on the template's Send By Schedules tab doesn't hold it back either. It sends the template on its own timetable, apart from the event.

Let the task carry the date instead. Build a GI on tasks and put a second business event on it, Trigger by Schedule, run daily, with conditions for Due Date equals @Today and the task still open, so finishing the task early means no email. Give that event an email subscriber. One catch: your template leaves Related Account blank, so the task isn't tied to the business account. Fill it from your GI so the task GI can reach the account and your NEXTCONT fields.

Thanks ​@Steve Milner I tried your suggestion; the task was created but none of the date fields populated properly.
