authorization of business partner Solution Manager ITSM

Hi,

I have a question regarding an authorization of business partner in Solution Manager ITSM.

In ITSM, CRM Business Roles are different according to business partner. For example, Requestor, Dispatcher and Processor.

and these roles have different CRM Web UI.

Requestor has a special CRM Web UI below screen capture.

and Processor has a special CRM Web UI below screen capture.

I want to change requestor's crm web ui from original crm web ui to processor's crm web ui.

to change the crm web ui role.

I copied solmanpro role and cusotomized solmanpro  business role.

repoter is assigned automatically in original requestor's crm web ui like 'repoted by: solman_admin'

After changing the requestor's crm web ui, manually reporter should be selected in reported by input field.

However requestor's authorizations are missing, when I select the reported by input filed, I can't input business partner.

what authorizations are related with this business partner 'reported by'?

Please reply me.

Thanks.
