Default Currency Conversion Type when SO currency is other than USD using OM Extension

Summary:

HI

Functional Currency is USD. When sales order is enter using currency other than USD then 'Corporate Currency'. Pre-transformation rule is not available for currency conversion type defaultation. So I am trying with groovy script in order management extension.

def currency = header.getAttribute("TransactionalCurrencyCode");

if (TransactionalCurrencyCode!= 'USD') {

  header.setAttribute("CurrencyConversionTypeCode", "Corporate");

}

The validation of the script is successful but it given an error when we create the sales order
