I think we can also use system debugging option to debug Macro as well.. :smile:

Hi Janagar,

Thank you for your information. I just tried in my system, and I could not debug the macro using system debugging. Would you please kindly share how you achieve that?

best regards,

Jerry

Hi Jerry,

Nice blog indeed, but the problem is,,

This is where I get stuck. :sad: :sad:

IMHO here is how to use macros wisely: don't use them.

This is a fad & i'm sure macros cannot be debugged with the system debugging option turned on ... ℹ

Hi Ankit,

Regarding the BYTE CODE, if you are referring to the screenshot in my blog, I don't think it is difficult to understand their meaning since they look something like ABAP command. But if you are referring to code like "xper 06  2F0C  0018  0016  ", I am afraid there is no public documentation on them. Why do we application developer need to understand them? Just out of curiosity? :smile:

Best regards,

Jerry

I haven't beforehand but now I have. Well.. I still have the same opinion. The reasons given in this blog or not enough: I disagree with some of them (code readability using macros) and some are not common problems when using ABAP (defining DSL).

My point of view is simple:

1 - They won't be debugged. Note that to debug a macro you have to know that it exists in your code. What if you set a breakpoint for all "PERFORM"s in code? The ones inside a macro won't stop the execution of the program. What if you set a watchpoint for a variable changed inside a macro? It will stop way after the macro. Moreover, there are many functional consultants who although are not able to write ABAP code, are able to read and debug it. So when it comes to readability in ABAP, I wear a functional hat and ask myself if a functional would be lost after a piece of code. In case of a macro, definitely he would be lost after a single line of code have changed many variables all at once.

2 - Macros are faster: yes indeed. However based on my experience in 90% of performance issues the most timing consuming code I have founded is within SELECTions in the database and searches inside internal tables. In other words, if you can write good SELECT statements and know how to use other types of internal tables other than STANDARD, it's very likely your code won't have any performance problems.

3 - You cannot unit test a macro. And that's why I don't use PERFORMs either.

Cheers,

Fabio Pagoti
