The Incident Parent and Child Poller Guide demonstrated how you might poll for updates from the table API of your PDI, but poll in two stages - an initial light poll, periodically scanning for updated records and a subsequent, on-demand poll, pulling back more detail from the relevant records and deciding how to process that data with the relevant inbound Messages. We will edit the Child Poll Processor so that it also kicks off another on-demand poll, scanning for attachments.
