Can i show template inside a variable

[Debasis Pati]

Hello All,
I want to have a template where i will have some patient details.
like name ,age,gender like these will be questions.
and these questions even i can store in a table as well i have a custom table even i can reuse that if we need.

My requirement is when i select option insurance type as health for example i have a variable called patient details these template questions should be applied and user should be able to select also and fill it .
Can i achieve this somehow either by using multiline variable set or using templates or something.

@Ankur Bawiskar any suggestions?

   //Type appropriate comment here, and begin script below

var my_var = g_form.getField('testingone');

Hi @Debasis Pati !!

Yes, this requirement can be achieved in ServiceNow, but with an important design consideration.

ServiceNow does not support dynamically creating catalog variables at runtime from a table. Catalog questions must exist at design time. However, you can still meet your requirement using Variable Sets or Multi-Row Variable Sets (MRVS) with conditional visibility.

Recommended Approach

1. Create a Variable Set (template)

   • Create a Variable Set called Patient Details

   • Add questions like Name, Age, Gender, DOB, etc.

   • This acts as your reusable template

2. Add Insurance Type variable

   • Create a choice variable insurance_type (Health, Life, Vehicle, etc.)

3. Attach the Variable Set to the Catalog Item

   • Add the Patient Details Variable Set to the item

   • Keep it hidden by default

4. Use a Catalog UI Policy

   • Condition: insurance_type = Health

   • Action: Show the Patient Details Variable Set

   • Else: Hide it

When the user selects Insurance Type = Health, the patient detail questions are displayed and can be filled in.

If Multiple Patients Are Required

If one request can include multiple patients, use a Multi-Row Variable Set (MRVS) instead of a normal Variable Set. Each row represents one patient.

Storing Data in a Custom Table

You can store the submitted patient details into your custom table using:

• Flow Designer (recommended), or

• A Business Rule on the request

I don’t think we can call a template from a variable. You need to use the variable only to get the data in MRVS form.
