How can I create a metric that would show me the date and time of the last time the data was updated within GoodData? Is it even possible? I'm trying to create such a metric that displays it inside a dashboard in the following format: "This data has been updated XX/XX/XXX at 00:00".
you need to add a new disconnected dataset to your logical model. The dataset should have a couple of columns:
Also, you can create a variable (type filtered value) using the timestamp attribute and add it to the dashboard using variable status. Once such dataset is uploaded, create a simple report including the timestamp attribute and add it to your dashboard.
