Unable to find standard workset --- Portal Display

Hi Experts,

Wish you a very happy new year 2011.

I am using EP 7.0. I am unable to locate 'Portal Display' workset. This workset contains following items:

1) Theme Editor Page

2) Theme Transport iView

3) Desktop and Display Rule Page

4) ITS Theme Generator Page

5) Theme Integrity Test Page

I can see 'System Administration' workset at Content Administration --> Portal Content --> Content Provided by SAP -->Admin Content -->System Administrator --> Worksets --> System Administration.

'System Administration' workset contains 'Portal Display' workset. I can not find 'Portal Display'. I tried to use Trace Delta Link to see the location of 'Portal Display' workset. However I am unable to find it.

I am even unable to find the location of followng portal items:

1) Theme Editor Page

2) Theme Transport iView

3) Desktop and Display Rule Page

4) ITS Theme Generator Page

5) Theme Integrity Test Page

Can you please help me.

Regards,

Gary
