I needed to understand the concept of these terms in d365fo x++, and where we can use them?

    It's not which maps are you interested in. There are table maps, such as SalesPurchLine, that allow using common logic for multiple tables (such as both SalesLine and PurchLine). And there is also a collection class called Map.
     
    A macro basically allows you to name a piece of code and then insert it in your code. Their main purpose in X++ used to be to define constants, but you shouldn't do that anymore, because X++ now has 'const' keyword for this purpose.

    (I moved the question from the AX forum here and removed d365fo from the title, because this whole forum is about D365FO and there is no need to repeat it in titles.)
