Recently I found there is a good object "Query" in Navision 2016. , there isn't such object in 2009.
But what I am worried about is the performance of it. I can combine header and line table easily, but if there is a method to create a key Or "index" ?
any suggestion will be warmly appreciated.
Thanks Erik, I got it. Hope you everything goes well, My friendly teacher, You helped me a lot. I am a "Question-boy".
