Downloading items with the UOM

Hi Terry,

We have a created a new UOM called fwm_uom  with the following lines

Abb:Abbrevation  , conv Rate :Converion Rate

Name  Plural Name   Abb   Plural Abb  Conv Rate(/Base)   Base unit
PA      PA    PA PA  1  YES

CSE    CSE  CSE  CSE  6  

PLT     PLT PLT        PLT        12

And we have created an item with   unitys type as fwm_uom . But when we try to download that particular item we are able to getting only Baes unit (PA) , but not the remaining (CSE,PLT). But for our Application we need the Item with three uoms(PA,CSE,PLT).
Is there any way to get the item with the three uomlines (PA,CSE,PLT).
