Forum Post: VI Import job error 46

I am doing an import job in Purchase Orders in MAS200 ver 4.50. I want to caculate a PO# based on temp field value. It is mostly 2 chs + some charactes from input date. when running a test, it gives an error 46 on VIWI0C on line 0134. I abaondoned constructing PO# and assign a specific PO# but it still gives me error 46 but different line. Any ideas? Is there rounding function in VI? after calculating amount I would like round it to the nearest penny. Thanks.
