Restricting vendors -any user exits please?

Question

Hi,
I have a requriement where while creating Vendors they have configured in such a way that it has to be approved for all the create and change vendors. since there is some sensitive information like bank accounts and names .
now we have changed the requriement where in we need to restrict the information only for certain conditions
vendor employee account group B007 and company code 2001 and for rest they donot need any approval and can be directly created or changed.
Is there any user exit or any other way where we can put this restriction.
We cannot put the configuration for specific requirements either the configuration is on or off in total.
Any help would be greatly appreciated.
Thanks and Regards,
Ravi Kumar L

Hi Max,
In XK02 if we change any of the Sensitive fields(like name bank account,bank key...). then it pops up a message that document is saved but needs to be confirmed.
For confirmation we need to login to FK08 and then press the confirm buttom for that vendor.
Now our requirement is we need that confirmation for some vendor employee account group B007 and company code 2001 and for rest they donot need any approval and can be directly created or changed.
As Suggested by Himanshu and You I have been in touch with the Basis guys for the creation of a Z object and authorization so that i can call the Authorization object in the user exit.
they too are not sure. so i need to confirm them so that they can go ahead with the creation of the z object. Since this involves business we need to tell them if this is possible or not fore hand and take their approval.
Can you suggest if we are going in the right direction.
Thanks,
