The Grantee Contact Person tab information is actually stored in the Relationship table.
Most foundations have a relationship type of "GC" that indicates a grantee contact.
The value used by you can be discovered and controlled in Tools > System Utilities > System Options.
Choose Grants, then Default_Grantee_Contact_Relationship and in the last column you can change or see your chosen value.
The value given when we implemented the feature was GC.
If you create a datagrid in profiles use a Profile, Relationship table combination. If you create one in Grantees, use a Grantee, Profile, Relationship one. Make sure you select on Relationship type of "GC" on the selection tab.
Once you have created your grid you can report on or export the information using the Processes icon.
