Before Record Submit

action in a NetSuite workflow. This action can employ either a custom script or a formula that iterates through the line items to find the highest value. If scripting is an option, SuiteScript could be used to loop through line items to find and set the highest value on the body field. Here’s a simplified pseudo-formula for illustration:

CASE 
  WHEN {item1} > {item2} AND {item1} > {item3} AND {item1} > {item4} THEN {item1}
  WHEN {item2} > {item3} AND {item2} > {item4} THEN {item2}
  WHEN {item3} > {item4} THEN {item3}
  ELSE {item4}
END

This formula checks which line item has the highest value and then populates the body field with that value. Note that you’ll need to replace

{item1}, {item2},...

, with your actual line item field references. If you have more than a few lines, or if the lines can change, a scripted approach would be more dynamic and maintainable. However, it's important to note that you cannot perform calculations in real-time. You can source values but you can’t calculate values from different fields. To do calculations it requires a server-side trigger with workflows like before submit or after submit. Alternatively, you could do this with a client script if you aren’t using the items Sublist or really need it in “real-time” while editing the line.
