Global macros
In a previous article we talked about macros, a relatively obscure and little used feature that can be both useful as well as create a huge mess. But these aren’t the only ABAP macros. There are others that are even more obscure and with even greater potential to mix up a system: the global macros. I don’t know if I should tell you this, as it’s so strange… But, I don’t think it’s a good idea to hide it… Therefore, I’ll tell all.
