Granting a proxy access to a subsystem does not change the permissions for the principal specified in the proxy.

Only members of the sysadmin fixed server role can execute sp_grant_proxy_to_subsystem.

A. Granting access to a subsystem by ID

USE msdb ;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
    @proxy_name = 'Catalog application proxy',
    @subsystem_id = 2;
GO

B. Granting access to a subsystem by name.

USE msdb ;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
    @proxy_name = N'Catalog application proxy',
    @subsystem_name = N'Dts' ;
GO
