Embedded list in servicenow

Praju_123 — Wed, 10 Sep 2025 10:19:49 GMT

On the native UI form, we have added an embedded list. We want the system to calculate the total claim amount only when the user enters data into the embedded list, and update the Total Claim Amount field accordingly.
It will make calculate the total of claim field which is in the embedded list and total will store into the total claim amount field.

i.e. currently we have two records in the embedded list so the total of claim amount is 958 so it will 958 in the total claim field

This calculation should happen before the form is submitted, without saving the claim record.

Currently, we are able to achieve this calculation on form submission, but our requirement is to perform the calculation before the form is submitted.

@Praju_123

you can run after insert BR on your embedded list table and then sum up all the values for the parent and update the parent record.

With this if you see the updated value on form then good.

if this doesn't work then your user need to reload the form.

Hi @Praju_123 ,

You can achieve this using the onCellEdit functionality on the embedded list.

Since your requirement is to calculate the total claim amount before the record is submitted (while the user is editing the embedded list), a Business Rule won’t work because that only runs after save. Instead, you can configure an onCellEdit Client Script on the child table (the one shown in the embedded list).

How it works:

The onCellEdit script runs as soon as a user edits a cell in an editable list.
You can capture changes to the Claim Amount field, sum up all claim line values, and then use g_form.setValue() to update the Total Claim Amount field on the parent form dynamically.
This way, the parent field is updated in real time without saving the form.

In short: Yes, it’s possible, configure an onCellEdit script on the child table, calculate the total of the claim amount field, and set that total into the parent form’s Total Claim Amount field.

Thanks & Regards,
Muhammad Iftikhar
