Index Page Launched in NWBC Desktop

Hi Guru,

I had tried Two Methods for launching NWBC namely:

1) NWBC Desktop Client 5.0 with Setting->Personalise-->Entry Page: Index

2) NWBC Shortcut "sap-nwbc:http://server:8005/sap/bc/nwbc/~canvas/transaction/pfcg

Then the Result is launching of

Then My Questions are

A) Why Method 1 not able to view the same Index page like Method 2.

B) Why There is additional "Role Maintenance" Tab apart from the Index page being displayed.

Thanks in advance for your input.

Regards,

Matthew
