ServiceNow Interview Questions
Catalog Item
1. What is a Catalog Item in ServiceNow?
A Catalog Item in ServiceNow is a form used to submit information, a request, or to create a task. Catalog Items contain questions that gather information from users to create a record in a table. They are part of the Service Catalog and can include workflows, approvals, and tasks.
2. What is the difference between a Catalog Item and a Record Producer?
A Catalog Item is used to generate a request, complete with workflow, tasks, and approvals. A Record Producer, on the other hand, is used to gather information using variables (a form) but creates another type of record, such as an incident, change, or problem.
3. How do you associate a workflow with a Catalog Item?
To associate a workflow with a Catalog Item, navigate to the Catalog Item form, and in the “Process Engine” tab, select the desired workflow from the “Workflow” field. This workflow will be triggered when the Catalog Item is requested.
4. What are Variable Sets, and how are they used in Catalog Items?
Variable Sets are reusable groups of variables that can be added to multiple Catalog Items. They help in organizing and managing variables efficiently. By using Variable Sets, you can avoid duplicating variables across different Catalog Items.
5. How do you use User Criteria to control access to Catalog Items?
User Criteria in ServiceNow defines conditions that are evaluated against users to determine which users can access specific Catalog Items. You can set User Criteria in the “Available For” and “Not Available For” related lists on the Catalog Item form to control access based on roles, groups, locations, or other user attributes.
6. What is an Order Guide, and how does it differ from a Catalog Item?
An Order Guide in ServiceNow is a tool that allows users to order multiple related Catalog Items as part of a single request. It guides users through a series of questions to determine which Catalog Items to include in the order. Unlike a single Catalog Item, an Order Guide can bundle multiple items together.
7. How do you handle dependencies between variables in a Catalog Item?
Dependencies between variables in a Catalog Item can be handled using Catalog Client Scripts or UI Policies. These scripts and policies can dynamically show, hide, make mandatory, or set read-only states for variables based on the values of other variables.
8. Scenario: You need to create a Catalog Item that is only visible to users in the Europe region. How would you implement this?
I would set the User Criteria for the Catalog Item to include only users in the Europe region. This can be done by navigating to the “Available For” related list on the Catalog Item form and adding a User Criteria that specifies the Europe region.
9. Scenario: You need to populate the logged-in user’s information in a variable on a Catalog Item form. How would you achieve this?
I would use a Catalog Client Script to populate the variable with the logged-in user’s information. Here is an example script:
JavaScript
function onLoad() {
var user = g_user.userID;
g_form.setValue('variable_name', user);
}
10. Scenario: You need to create a single workflow for multiple Catalog Items with slight modifications. How would you achieve this?
I would create a generic workflow that includes conditional logic to handle the slight modifications for each Catalog Item. This can be done using workflow activities such as “If” conditions, “Switch” activities, or custom script activities to differentiate the processing based on the Catalog Item requested.
11. Scenario: You need to create a Catalog Item that triggers different workflows based on the user’s department. How would you achieve this?
I would create a Catalog Client Script to determine the user’s department and set a hidden variable with the department value. Then, I would use a single workflow with conditional logic to branch based on the department value. Alternatively, I could create multiple workflows and use a script to dynamically select the appropriate workflow based on the department.
12. Scenario: You need to ensure that a Catalog Item is only available during specific business hours. How would you implement this?
I would create a Catalog Client Script to check the current time against the defined business hours. If the current time is outside of business hours, I would display a message to the user and prevent the submission of the Catalog Item. Here is an example script:
JavaScript
function onLoad() {
var currentTime = new Date();
var startHour = 9; // Business hours start at 9 AM
var endHour = 17; // Business hours end at 5 PM
if (currentTime.getHours() < startHour || currentTime.getHours() >= endHour) {
g_form.addErrorMessage('This Catalog Item is only available during business hours.');
g_form.setReadOnly('submit_button', true);
}
}
13. Scenario: You need to create a Catalog Item that requires approval from multiple approvers in a specific order. How would you configure this?
I would create an approval workflow for the Catalog Item with multiple approval activities. Each approval activity would be configured to require approval from a specific approver. The workflow would be set to proceed to the next approval activity only after the current one is approved, ensuring the approvals occur in the specified order.
14. Scenario: You need to pre-populate a variable in a Catalog Item with data from an external system. How would you achieve this?
I would use a Catalog Client Script to call a REST API or SOAP web service to fetch data from the external system. The script would then populate the variable with the retrieved data. Here is an example script:
JavaScript
function onLoad() {
var request = new XMLHttpRequest();
request.open('GET', 'https://api.example.com/data', true);
request.onreadystatechange = function() {
if (request.readyState == 4 && request.status == 200) {
var response = JSON.parse(request.responseText);
g_form.setValue('variable_name', response.data);
}
};
request.send();
}
15. Scenario: You need to create a Catalog Item that dynamically updates the available options in a dropdown variable based on the user’s previous selections. How would you implement this?
I would use a Catalog Client Script to update the options in the dropdown variable based on the user’s previous selections. The script would use the g_form.addOption() and g_form.removeOption() methods to dynamically modify the dropdown options. Here is an example script:
JavaScript
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.clearOptions('dropdown_variable');
if (newValue == 'option1') {
g_form.addOption('dropdown_variable', 'value1', 'Label 1');
g_form.addOption('dropdown_variable', 'value2', 'Label 2');
} else if (newValue == 'option2') {
g_form.addOption('dropdown_variable', 'value3', 'Label 3');
g_form.addOption('dropdown_variable', 'value4', 'Label 4');
}
}
16. Scenario: You need to create a Catalog Item that dynamically updates the available options in a dropdown variable based on the user’s previous selections. How would you implement this?
I would use a Catalog Client Script to update the options in the dropdown variable based on the user’s previous selections. The script would use the g_form.addOption() and g_form.removeOption() methods to dynamically modify the dropdown options. Here is an example script:
JavaScript
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.clearOptions('dropdown_variable');
if (newValue == 'option1') {
g_form.addOption('dropdown_variable', 'value1', 'Label 1');
g_form.addOption('dropdown_variable', 'value2', 'Label 2');
} else if (newValue == 'option2') {
g_form.addOption('dropdown_variable', 'value3', 'Label 3');
g_form.addOption('dropdown_variable', 'value4', 'Label 4');
}
}
17. Scenario: You need to create a Catalog Item that requires approval from multiple approvers in a specific order. How would you configure this?
I would create an approval workflow for the Catalog Item with multiple approval activities. Each approval activity would be configured to require approval from a specific approver. The workflow would be set to proceed to the next approval activity only after the current one is approved, ensuring the approvals occur in the specified order.
18. Scenario: You need to pre-populate a variable in a Catalog Item with data from an external system. How would you achieve this?

if (request.readyState == 4 && request.status == 200) {
var response = JSON.parse(request.responseText);
g_form.setValue('variable_name', response.data);
}
};
request.send();
}

var currentTime = new Date();
var startHour = 9; // Business hours start at 9 AM
var endHour = 17; // Business hours end at 5 PM
if (currentTime.getHours() < startHour || currentTime.getHours() >= endHour) {
g_form.addErrorMessage('This Catalog Item is only available during business hours.');
g_form.setReadOnly('submit_button', true);
}
}
21. Scenario: You need to create a Catalog Item that requires approval from a dynamic list of approvers based on the user’s input. How would you configure this?
I would create a Catalog Client Script to gather the user’s input and dynamically generate the list of approvers. This list would be stored in a variable. In the workflow, I would use a script to read this variable and create approval tasks for each approver in the list. Here is an example script for the workflow:
JavaScript
var approvers = current.variables.approver_list.split(',');
for (var i = 0; i < approvers.length; i++) {
var approval = new GlideRecord('sysapproval_approver');
approval.initialize();
approval.approver = approvers[i];
approval.source_table = 'sc_req_item';
approval.source_id = current.sys_id;
approval.insert();
}

}
g_form.clearOptions('dropdown_variable');
if (newValue == 'option1') {
g_form.addOption('dropdown_variable', 'value1', 'Label 1');
g_form.addOption('dropdown_variable', 'value2', 'Label 2');
} else if (newValue == 'option2') {
g_form.addOption('dropdown_variable', 'value3', 'Label 3');
g_form.addOption('dropdown_variable', 'value4', 'Label 4');
}
}
