Hi Experts,
I am trying to extend MDGC 7 in my demo system with the help of this guide: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0375d58-2161-2f10-e285-c6078fcb8f43?QuickLink=index&…, but I cannot find the required field in the UI configuration.
I've extended the KNVV table:

Extended the BP data model:

Activated it, then Generated Selected Structures

Then I did the SMT mapping steps where the options seemed to be a bit different than the ones in the document:



Then I adjusted staging area of linked change requests.
Then I displayed the page in customizing mode and selected a UIBB, clicked on "Add elements", but I cannot find the relevant field anywhere.

Could you pleae help me?
Many thanks in advance,
Tamas
