Suggest for NWBC screen problem.

Hi experts.

1-I'm working with TM/BOPF/WEB DYNPRO  and i created a program that create a order with items.

Then i SAW This ITEMS with header in /n/bobf/test_ui transaction like this image below:

Then i go to see it in NWBC transaction.

And the items dont are  displayed.

Should I open call with sap to see this screen or there exist a way to debug this NWBC screen?

Thanks for help.
