Am a newbie to qlikview. I have one doubt in QVD's. For Eg: if i have one QVD with 1000 records already loaded. And tomorrow if i load the QVD again from the same source and in the source some values were updated but still the records are 1000 only. Then if i load QVD again will it get a new data or the same old data persists? For loading new data we need to follow any approach if its the case?
