Error "Item is not defined as an Inventory Item" using oInventoryGenEntry

Question

I am trying to create a Receipt from Production with this code:
                receive = (Documents)_Company.GetBusinessObject(BoObjectTypes.oInventoryGenEntry);
                receiveLine = receive.Lines;
                        receiveLine.BaseType = 202;
                        receiveLine.BaseEntry = oli.ProductionOrderNumber;
                        receiveLine.BaseLine = 0;
                        receiveLine.Quantity = oli.Quantity;
                        receiveLine.WarehouseCode = "01";
                int errorCode = receive.Add();
where the production order will contain several component items that make up a finished good.  Two of the component items are Labor and Royalties and are not marked as Inventory Items.
The Add method returns this error:
"Item is not defined as an Inventory Item" and references one the non-inventory items (ie 'Labor').
I can received the same Production Order through SBO without an error.
Suggestions?
Thanks

Answer 1

Because I am concerned about eliminating Labor from the Bill Of Material and its effect on the 'Acutal Product Cost' when I create a Production Order I set up a test.
I created two Finished Goods Inventory Items with similar Bills of Material.  Both included a Labor component (non-inventory item).  The difference though, is one Labor component has an Item Type of Labor and the other Labor component has an Item Type of  'Items'
Next, I create a Work order for each of the finished items.  Then I did a receipt from Production and closed the Work Orders.
Looking at the Production Order summary, the Finished Good had an 'Actual Additional Cost' that was non-zero for the Finished Good that had a Labor component of the 'Items'; the other Finshed Good had a zero 'Actual Additional Cost'.  These seems in conflict with the eLearning segment on Production.
At this point is this a different Forum?
