MSS Work Overview page - How to add/remove columns from the table

Hi SAP Net Weaver Gurus

In the past I have configured OADP columns with a "Z" configuration ID
in the Java portals and then created an Iview referencing the "Z"
configuration but how does it work with Net Weaver EHP7 (NWBC) ?

Should I still configure OADP to change the columns ? How do I
link Net Weaver to my Z configuration ?

Please see the attached pic to see the table where I need to add the columns

Thanks in advance
Jack
