SRM7 - External number screen

Hi,

When users login to SRM7 and access Contract management then click on “create central contract” as in screen1, a pop up screen
(screen 2) should appear where they can enter External number.

This screen2 (where they can enter External number)appears only when we use the SAP standard role. But we would like to include this functionality in the customizaed role.

I would like to know what access or configuration setting should be setup to achieve this functionality?

//Thanks,

Nazeeha.
