Re: Copy an entire dashboard
@damen Yes, if you click the wrench in the top right corner of the dashboard and select "Save As" you can copy an existing dashboard.
Re: Dataset refresh failure notifications
We had a similar use case and created a group email address, set up a user in Domo with that email, and then made that user the owner of the process the group needed a notification about.

Re: Dataset refresh failure notifications
Currently it's not an option until they allow group ownership of datasets. You could utilize an email address that would then forward emails to a group but that would have to be handled in your email server outside of Domo.
Re: Dynamic Rank Beast Mode
Are you using RANK in a window function? It sounds like you don't want any missing numbers in your sequence. Rank will ignore numbers if there are ties in your dataset. In this case you might want to try DENSE_RANK instead as that won't have any skipped rank numbers.
Re: Return most recent row/date
@AdamC You can use a Rank & Window tile:

Using Row Number as the function, then ordering by EVENTTIME descending, and partitioning by EQUIPMENT_NUMBER. This new column that's created will assign the most recent date for each equipment number a value of 1 and you can just filter to only allow where the row number is 1.
