Do you have PNRs in Sabre that you want to import into the itinerary you will be creating?

Before even starting your itinerary in Umapped, start by placing the Sabre PNRs you want to add to your Umapped itinerary onto the 'Umapped queue' in Sabre.

The Umapped queue in Sabre is 500 (PCC = 3WRG)

You can use the queue format QP/3WRG500/19
