I'm testing Qlik Sense 3.0, and my first need is to get it to recognize my dates as such (they're in ISO format, I don't know why it can't figure this out on its own, but anyway). So I go to Data Manager, select my data source, click the edit button, and see "Add field" in the top-right. Trouble is, it's disabled, with no indication as to why.
Why might the "add field" button be disabled?
I can rename fields, so the data source is not completely locked down. The source was two .CSV files, automatically concatenated; can one not add calculated fields to a concatenated data source? I'm not using a manual load script.
