Creating a view in One Identity

I've created a view in One Identity but when I try to view a single object of the view in Object Browser, it returns an error:

[810351] The table TableName has no primary keys. That's why it can only handle collections of objects. Single objects cannot be created for this table.

I can't make one of the columns as primary as it is greyed out.

Can I fix the error or do I need to delete the view and start over?
