Lookup Tables provide a centralized way to define and manage key‑value mappings for integrations. Instead of hardcoding values in workflows, administrators can configure source‑to‑target mappings once and reuse them across flows. This streamlines data transformation, ensures consistency, and simplifies integration maintenance.
Benefits
Simplifies data mapping across different applications using reusable lookup values.
Ensures consistent data transformation by centralizing mapping logic across integration flows.
Centralizes value mappings in a single location.
Configure Lookup Tables
To configure Lookup Tables, perform the following steps:
Navigate to Integration Platform > Lookup Tables.
The Lookup Tables list page is displayed.
Figure: Lookup Tables - ListClick + New Table to create a new table.
The New Table page list is displayed.
Figure: New TableEnter the new table Name in the textbox and click Create.
The Lookup Table page is displayed.

to add a Column and row to create a table for mapping.

If you are integrating ServiceNow with Apex to automatically create incidents in Apex whenever a new incident is created in ServiceNow. Create a Lookup Table as displayed, because both applications use different values for incident attributes, Lookup Tables are used to translate these values before creating the Apex record.

Lookup Table in Integration Flow
The mapping converts ServiceNow incident values into their Apex equivalents. When an incident is created in ServiceNow, the integration flow automatically applies these mappings before creating the corresponding incident in Apex.
To Configure Lookup Table in Integration, perform the following steps:
Navigate to Integrations and create a New Integration for mapping.
The Designer Canvas is displayed.
Figure: Designer CanvasCreate and configure a Webhook trigger to start the integration flow when a new ServiceNow incident is created and receive incident details from ServiceNow.

Figure: Webhook - ConfigConfigure a Lookup Table to maps the required field values before the data is processed by the destination application.

Figure: Configure - Lookup TableSelect the required lookup table, configure the source and target columns, map the ServiceNow fields (such as Urgency, Impact, and Priority) to their corresponding Apex values, and specify default values for unmapped entries.
On creating a ServiceNow record, create an Apex record and configure it to create an incident in Apex.

Map the transformed lookup table values and other incident details, such as Caller, Description, Status, and Symptom, to the corresponding Apex fields.Add a Custom Code component to convert the attachment object received from ServiceNow into a list of file names.
Add a Loop component to process each attachment individually.

Inside the loop, configure the Get Attachment component to retrieve each attachment from ServiceNow and the Upload Attachment component to upload it to the newly created Apex incident.Save and Deploy the integration flow to verify that incidents.
