Delivery id for recurring delivery

[Kabeiro]

Hi,
I'm trying to create a workflow that send 2nd email after 1st email sent 3 days ago, they will be both recurring delivery.

The problem is when I try to query by delivery log id = 1st email delivery id,   it is not working, the recurring delivery creates a sub delivery with auto generated delivery id for each reporting aggravation period.

Thanks.

Thanks, found it, it's "id of primary instance of delivery"
