Issue related to Authorization Concept

Hi Friends,

In Authorization Concept, generally we define authorizations(roles) considering T-codes and we will assign them to respective user groups through profiles.

My issue is can we restrict the user to use particular screen or field instead of entire transaction?

For example, user 'A' has the authorization to use T-code MM02.Suppose he belongs to MRP Department.I want to give him authorization to operate with only one MRP view instead of all four MRP views or in a particular view (say MRP1) one or two fields.Is it possible to do like that?

I request you to suggest on this issue.

Thanks in advance.

Regards,

Rajarao.
