When a WSDL for the target Incident table is requested with an additional parameter of
hierarchical=true, the WSDL schema for the Insert
function will reflect available related records that may participate in the hierarchical data
payload.
For example, the insert portion of the schema of the incident table, when requested with
hierarchical=true displays its hierarchy as follows:

https://instance.service-now.com/incident.do?WSDL\&hierarchical=true

...  
Figure 2. WSDL Schema Continued

The WSDL above shows the incident table having a related table
`u_custom_comments` that itself has a related table
`u_comment_items`.
