SAP SD Transaction codes List

I found a way to know hidden customizing Tcodes.

Before executing customizing task you desire, point it and go to Edit-Display IMG Activity. Then mark activity.

Go to T.Code se16 and type in CUS_IMGACH table. 
Execute. 
Paste IMG Activity and run. 
You will see Tcode that belongs to IMG Activity.
