Hi,
Please check this sample program to find BADI and enhancement for a given transaction code. You just need to create a custom program in your system by cut and paste below codes.
REPORT ZTEST.
TABLES: TSTC,
TADIR,
MODSAPT,
MODACT,
TRDIR,
TFDIR,
ENLFDIR,
SXS_ATTRT ,

To learn a BADI the best place are:

/people/sergey.korolev/blog/2005/03/14/the-time-for-me-to-have-a-badi-of-my-own
BADI comprises of 2 parts:
First is definition which you do in SE18.
Then comes the implemantion where you will write your custom code in SE19.
Try to go through the link, you will get enough info to proceed .
Also check this example ...
First you need to implement the 2 BADIs in SE19.
The BADI ME_GUI_PO_CUST is responsible for Screen display and data exchange b/n db and the screen.
The second BADI ME_PROCESS_PO_CUST is responsible for PO upadate.
To get the screen in the Transaction you need to code in the method SUBSCRIBE of the first BADI.
Example:
ls_subscriber-name = subscreen4.
ls_subscriber-dynpro = 0700.
ls_subscriber-program = prog_name.
ls_subscriber-struct_name = structure.
ls_subscriber-label = TEST.
ls_subscriber-position = 4.
ls_subscriber-height = 6.
ls_subscriber-height = 8.
append ls_subscriber to re_subscribers.
clear ls_subscriber.
