MBO Columns Display...

Hello Experts ,

    I have a doubt regarding MBO(Mobile Business Object) In SUP... I Created an MBO based on an RFC(Remote Enabled Function Module) from SAP.

So RFC Contains around 30 fields , After creating MBO based on that RFC , I don't want all the 30 columns to display . So how to restrict the columns and minimizing the display. So where can we restrict the UN-necessary fields and What is 'Nullable' option at MBO level ...?

Appreciate Your help.

Thanks,

UK.
