Don't load the whole record for two fields

 Need a customer name and email inside a SuiteScript? Loading the full record is the easy habit — and usually the expensive one.

Use search.lookupFields when you only need a handful of values:

var fields = search.lookupFields({
  type: search.Type.CUSTOMER,
  id: customerId,
  columns: ['entityid', 'email']
});

var name = fields.entityid;
var email = fields.email;

Why it wins:

• Fewer governance units than record.load
• Faster on big records with lots of sublists
• Clear intent: “I only need these fields”

Rule of thumb: if you’re not editing the record, don’t load it. Lookup what you need and move on.
