DBI to fetch user's role in a fast formula

Content

Hi All

 

We have a requirement to allow editing of absences only for users having specific roles.

The plan is to write a fast formula of Global entry type validation formula and restirct the editing based on user's role. 

 But I am not aware of any DBIs that can be used to fetch a user's role in a Fast formula.

Can anyone help me with the DBI?

 

 

Thanks
