I want to know how FBR integration is done in AX 2012. Please guide me through the complete procedure with code. Also, the invoice that is sent by FBR must be saved in a table.
I did a quick search and found a blog with code examples that seems to match your FBR question on this subject, see link below.
I am of course assuming it's the same subject in your post. I hope this gives you an idea and helps you. I have not fully read this blog or even know if it's working at all, so I can't endorse it or justify anything in this blog.
Even though the blog below is for D365 F&O it should be possible to adapt it for AX 2012.
