SAP Table For storing ABAP Source code

Hi All,

i have a requirement under which i need to know that where the source code of any method is getting stored.

For example .

If i have a method READ_DATA.

inside that i have written my code for reading data ie

select * from ZTAB into table lt_tab where key = k.

so my question is that where this above line is going to be stored.

Thanks & Regards ,

Abhishek
