Receivables 9.1A (131105)
I am doing an AR import (using an Excel file) to update the spec fields on the Invoicing tab of Customers.
(E.g. Invoice & Cr Note Print spec & Email spec fields)

Problem is, that it is not working properly.
I do not receive any error messages, but the fields simply do not get updated.
Even worse, if I had a value in the field before the import, the field is now blank.
