I'm trying to follow the instructions to create master calendar (Understanding the Master Calendar - Qlik Sense and QlikView - YouTube), but when I go to Data Load editor, I don't have the same view (time 3:20 in the video). I have Main and then Auto-generated section which is locked. There's Unlock button, but it gives scary sounding ultimatum ("If you unlock the auto-generated script, you will not be able to edit the data selection with Data manager. Unlocking cannot be undone.")
Shall I unlock or create new section for adding new fields (Month, Year)? If I create new section, do I need to copy that whole load script or just add new fields?
