I have used that before when dealing with Invoices and Cash Sales. The problem is, for this customer search, I don't want the whole balance, just the overdue balance. There is a Balance (foreign currency) field on customer, but no overdue balance in the foreign currency that I can find. NetSuite is inconsistent in how it handles that field. Through the UI (and in a User Event Script) I get the foreign currency amount, but through a saved search I get the converted amount in the base currency, using the same field in both cases.
