Once the Web Service is created, the next step is to start mapping these new fields to existing fields in ServiceNow's Incident table in the Table Transform Map form.
On the upper-left, set the name for the mapping
Name: (defaults to "Inbound LogScale Integration")
On the upper-right, set the target table:
Target table: Incident (defaults to Incident)
Click on at the bottom left of the screen to start mapping the fields.

A wizard will pop-up and you can map the following fields that we had just created. This will map which fields in an incident form will be populated by LogScale data. For example:
Summary ↔ Short Description
Full Description ↔ Description
Request For ↔ Caller
Incident Status ↔ State
Repository ↔ Additional Comments
Click once you've completed the mapping.
