FPM WDA, unable to implement interface to FPM_OIF_COMPONENT

[Former Member]

Good day!

My requirement is to change tab names in standard component dynamically at runtime.

I'm trying to implement code that is proposed in FPM Development Guide at page 73/74, "Changing the Tabbed Component Dynamically at Runtime":

Changing the Tabbed Component Dynamically at Runtime
You may rename, add and remove tabs or child-UIBBs (or embedded UIBBs) from
your tabbed component during runtime.
To do so, proceed as follows:
1. Choose an application-specific Web Dynpro component and add the Web
Dynpro interface IF_FPM_TABBED_CONF_EXIT to the Implemented Interfaces
tab of your Web Dynpro component. This is one of the Web Dynpro
components that provide you with a child UIBB.

I created an enhancement and tried to change the tab "Implemented Interfaces" in component FPM_OIF_COMPONENT. But that tab is unavailable for changes even via enhancement.

For Z-webdynpro components I implemented that interface successfully.

What's wrong with standard WD-components?

This behavior is right, you can implement the interface for your own component and not enhance the standard component as in this case the FPM component is heavily used.

Yeah, in course NET311 (page 181) there said:

The following enhancement options do not exist for SAP NetWeaver 7.0:
• Create new custom controllers
• Create new events in existing controllers
• Enhance component interfaces
