Possible to make API call to notify users which filter-selected values are not available?
We're building a Qlik Sense mashup with a bunch of different data sources. Some of these data sources don't have data for all Countries.
If the users filter the country dimension on UK & US, how can I notify users that e.g. the Sessions metric only includes data for UK?
Right now we're making an API call for 'Sum(Sessions)'. So in addition to getting the number I would like to know which Countries and Brands that returns Null for this metric. Is this possible to do via the API?
