I have a QVD which has product details. The fields are product id, product name, price, update date.
Now a product price and product name can change for a product id. I want to maintain versions and later on using interval match I would like to see what was the price/name during that interval. The update data monitors the day of change.
Can someone explain how to put a from date and to date field to capture the change using a QVD.
Please have a look at the attached excel for the data. The product id 123 and 234 has both price change and name change.
