Today, we will explore the steps to create List UIBB with OVP in SAP FPM.
There are 3 main steps required to create a List UIBB with OVP.
- Overview Page Floorplan(OVP) objects-
- Create Web Dynpro Application,
- Web Dynpro Application Configuration and
- Component Configuration for OVP.
- Create Feeder Class for Form UIBB.
- Create Component Configuration for Form UIBB.
We’ll use the OVP Application and component configurations of the blog – Create Form UBIBB with OVP in SAP FPM
Creating Feeder Class for List UIBB – FPM_LIST_UIBB
Use the below code to create the Feeder class ZCL_FEEDER_FLIGHT_BOOKING_LIST.

Creating component configuration for List UIBB – FPM_LIST_UIBB
Open Web Dynpro component FPM_LIST_UIBB_ATS in T-code SE80.
Create a component configuration, by right clicking on the Component Configurations node and selecting ‘Create’ from the context menu.
A new web page ‘Configure Component’ gets open. Enter ‘Configuration ID’ as ‘ZCOMPCONF_LIST_FLT_BOOK’ and click on ‘New’.
Enter the description and click on ‘OK’.
In the ‘Select Package’ popup, click on ‘Local Object’.
Enter Feeder Class ‘ZCL_FEEDER_FLIGHT_BOOKING_LIST’ and click on ‘Edit Parameter’.
Click on ‘OK’.
On the Configure Component page, click on the ‘Column’ button as highlighted in the below screenshot and select the required columns from ‘Add Column’ popup.
The columns are added on the Configure Component page. Click on Save.
Now that our List UIBB is ready, let’s add it to the OVP component configuration ZWDA_OVP_FLIGHT_BOOKING_CNF, which was created in the blog Create Form UIBB with OVP in SAP FPM.
Go to Component Configurator from SE80 for Web Application ZWDA_OVP_FLIGHT_BOOKING, as shown in the below screenshot.
Click on ‘Continue in Change Mode’.
Click on the hyperlink for Component configuration ZCOMPCONF_OVP_FLIGHT_BOOKING, as highlighted in the below screenshot.
On the Configure Component page, scroll down to ‘Overview Page Schema’ section and click on ‘UIBB’ button. From the context menu, select List Component.
A new row gets added under Section. Maintain the Configuration ID as ‘ZCOMPCONF_LIST_FLT_BOOK’ and Title as ‘List of Flight Bookings’.
Finally, it’s time to test the application. Execute the Web Dynpro Application ‘ZWDA_OVP_FLIGHT_BOOKING’.
Web page ‘Flight Booking Details’ is launched.
Now that we have a List and Form UIBB on the same Floorplan, it makes logical sense to connect them using wiring schema, which is covered in the blog Create wiring between UIBBs in SAP FPM
