When the dataset uses Live Connect, it is not possible to set the frequency of email subscription. An email is sent whenever the dataset is refreshed. I would like to have the option to limit this to e.g. once a week or once a month.
Yes - we definitely need this. One of my client has an Azure Analysis Services model that gets refreshed several times per day. Power BI limits the subscription to no more than once per day, and that is absolutely fine - we just want to control at what time during the day, the email is sent.
