Lean Order OIF application - Sales Order - Item Overview - field Article

Hi colleagues,

my problem is that I do not find the view where the field Article(material) is located. The F1 technical details of the screen says the component and view are

appl LO_OIF_MAIN_APP

Web Dynpro Component: FPM_LIST_UIBB

View Information: V_LIST

but this view V_LIST is a configurable list UIBB (I do not know much about it) and it does not contains the fields in Item Overview subscreen.

I need to know that view because I have to change the field attributes for field Article.

By the way someone knows what view is this? or any tips to find it?

regards,
