Thanks guys. I will need to check with the app vender.
It has come to light that I may be able to get what I am after by extracting from a second dataset (logs stock movements). The dataset in question lists ProductId multiple times with a date the stock moved (some products moved multiple times on the same day). How might I construct a query that returns the last 5 dates per product?
The dataset in question has 200000 records (lots of repatition).
I would name the table StockMovements and it would ahve 2 fields 'ProductId', 'DateMoved'.
Many Thanks,
Phil.
