Best way to enhance TM WD4A Components?
I am new to TM area and in learning stages. My requirement is to enhance the layout for WD4A component 'FITE_VC_REVIEW' which is an integrated component within FITV_FPM. Which method would be better to enhance this? Create a Enhancement Implementation or make a 'Z' copy of this component? If I make a 'Z' copy then where in IMG I should map this custom component?
Also, how can I enable debug mode when I am running TM WD4A applications?
Are there any books or is there any help available that explains the technical area of TM? I am really having hard time finding help for this.
Appreciate your help.
Thanks and Regards,
