Hi,

Macros are used for code modularization.

The main advantage of macro is that it can be stored in the table TRMAC, and can be used by any program.

I once had a requirement.. where I was writing data to file... and the req demanded that the quant fields need to show a space rather than 0.00 when empty... for that I wrote a macro and that solved the problem...

Hi,

Macro can be used when you want to execute a particular code again and again. It is generally used for the calculation purpose.

for example

DEFINE calculate.

&1 = &2 + &3.

END-OF-DEFINITION.

DATA: l_var1 TYPE i,

l_var2 TYPE i,

l_var3 TYPE i.

Loop at itab.

calculate itab-var1 itab-var2 itab-var3.

endloop.

Hi Puneeth,

Modularization is done by using macros.

we can written reusuable code in Macros .

for ex: we can build field catalog using Macros ...

Macros reduces the coding effort.

Hope it hepful .

Thanks
