Best way to enhance TM WD4A Components?

[Former Member]

Hi,

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,

In my opinion you are almost always better using the Enhancement Framework than making a Z copy. However without knowing any of the details of what your enhancement entails it is difficult to make a firm recommendation. As this application sounds like it is Floorplan Manager based (FPM), you might see if your changes can be made with the component configuration of the FPM and not even need the enhancement framework.

There is no debug mode in Web Dynpro. You simply set an external breakpoint and when the breakpoint is hit the SAPGUI will launch with the ABAP debugger.

Thing is that the entire TM is built using several WD4A applications and each component is dynamically triggered based on user interaction. I am still debugging and trying to figure out the source where the component names are dynamically determined by the framework. I am assuming that probably there is some back-end customizing table where in I could do customer component assignment as replacement for SAP standards. Since I am not sure if there is any such back-end customizing table for components assignment I posted this question. But I too would agree that Enhancement Framework is better option than making a Z copy. It's just that I want to know for any such customizing table before I enhance it. I haven't used FPM before but my requirement is to add additional UI elements and bind custom content to it and I am not sure if I can do this via FPM configuration.

For debug mode, what I meant was that within FITV_FPM core TM component, I saw that there was a separate view called DEBUG_VIEW and I wanted to know how to enable it. But now I figured it out and it is through URL parameter SAP_FITV_DEBUG, which can have value 1 through 5 depending on the level of information user wants to see.

Hi Srinivas,

I have a similar requirement. A standard FPM Webdynpro component need to be modified, and I am new to FPM related developments. I need your assistance, for knowing how change Application specific changes.
