Is there a way to dot walk from a Target table to the Staged source Import set table?

Hello Snow Community,

In Vulnerability Response Security Exposure Management, there is a stage table named 'sn_vul_tenable_sc_vuln_import' which gets its data from using Tenable API. The table targets Vulnerable items [sn_vul_vulnerable_items] table. What I am looking for is to find a way to dot walk back to a field name 'u_repository' that exist inside the staged table. Now, I tried using the list view to filter out and Dot walk to that table records, but could find it. I am not sure if ServiceNow allows to dot walk from a target table to a staged table. If anyone has any information, please share. Thank you.

Target tables do not have reference fields back to the Import set tables. 

The only way to do this is via script.  You have the sys_id of the record in the Vulnerable Items table.  You'd have to query the import set table where the Target field is that sys_id.  But then you'd get all import records that updated that target record.

I don't know what you are trying to achieve here nor why you'd ever want to link back to the import record.

Hi Gaurav,

If I needed to do this, I'd create a Database View. DB Views allow you to join data from multiple tables into a single pseudo-table. It works by defining INNER JOIN logic between the connecting tables. This means if there's a unique identifier in your System Import Set (staging) table that matches a field in your Vulnerable Items table, you can set that as your joining logic. Example:

Table 1: sn_vul_tenable_sc_vuln_import - Variable prefix = vimport - Unique Identifier field = v_num (let's say)
Table 2: sn_vul_vulnerable_items - Variable prefix = vitems - Unique Identifier field = number (let's assume this is what was used as the coalesce field in the system import set).

Where clause logic: vitems_number = vimport_v_num

Note that creating Database Views requires [admin] role privilege. You can read more about using DB Views here: https://www.servicenow.com/docs/r/platform-administration/table-administration-and-data-management/c...

Hope that helps.
