No, it isn't easy to create because for me it works as expected.
There is something unique about your situation that isn't standard.
Please share more details of your circumstances.

PS. Your English is not a problem.

primary key? That will be enough for me: I will check if IBO created a
DB_KEY field: if so, I will use this field for my purposes, if not I will
choose the primary key field.
