Is there a way to create a roll-up summary field in NetSuite? Similar to how roll-up summary fields work in Salesforce?

Roll-ups are possible in a couple of different ways. One that I did recently was to calculate the total value of deposits that were made against a sales order to show the total of the deposits in a field on the sales order. What is the specific ask?

Thanks @Nicholas LaHara! I’d like to roll up subscription item data on to parent subscriptions, among other use cases. In Salesforce it’s a few clicks to create a roll-up summary field, but in NetSuite I can’t find any solution other than to write code. Is there a more declarative or point-and-click solution for setting up these kinds of roll-ups?
