Hi,
In AX 2012, if we use macro in the code, just declare #define in the beginning of the methods. How do we use Macro in AX 7 now?
Thanks,

In AX7 X++ now supports the const keyword.
It replaces most use cases of macros.
Have a look here for more details

Hi Yuji,
In short, macros are now used as constants in D365O have a look on this post to see how you can use both.
devserra.wordpress.com/.../macro-or-const-on-ax-7-what-use
You can use macros the same way we did it in AX 2012. However try to use "const", in some cases it's not possible. For instance
#localMacro.DateFilter
((priceDiscTable.FromDate <= toDate || !toDate)
&& (priceDiscTable.ToDate >= fromDate || !priceDiscTable.ToDate))
#endMacro
In this case you can follow traditional approach.
One small addition here: The use of macros was powerful to also reuse blocks of coding. At compilation the macro part will be inserted in the coding which takes additional compilation time. For this reason, try to avoid use of macros. Microsoft is aiming to get compilations as fast as possible. For this reason, it could be the case that macros will be depreciated in future, but I'm not sure about this.
In addition to performance, macros break a lot of development tooling. If you use macros to insert code blocks, none of the dev tooling can see that code. So things like code upgrade tools, visual studio add-ins, and any future tooling can never understand the macros, since those tools work against code, and macros are not "resolved" (/replaced) until compilation.
Take a look at the video from last years' AX technical conference about the new development environment, where we learned that Macros are Evil in AX 7.
