Hi All,
We working on getting line item details for a SalesOrder transaction through webservices.but the problem we are facing is how to get the item type(Inventory ,service and description items ..etc).We could not find any object where in i can get the item type.

for Ex: sample code
String line_no = salesOrderHeader.itemList.itemj].line ;
String item_rate = salesOrderHeader.itemList.item[j].rate;

similarly can we get the item type while getting the line item details?

We can do in one way ie for every line of transactions we need  get the item type from item master.But it will become performnace issue. for ex :if we have a salesorder with 100 items( lines) then we need to call API 100 times to get the item type from item master.
