Deleting an order line item with B1WS?

Question

Hi,
I am building an application which uses B1WS as it's interface to DISERVER.  There is a situation I am confused about and am hoping the folks here can shed light on.
I have an order object, and I would like to delete a line item from it.
How can I do that?
Thank you,
Mike

Ok, we figured it out.  I wasn't updating the LineNum property after resetting the line items.  The code below works for us, and  hopefully for you too.
Again, the idea is, to delete a line item, create a new line items collection and put into it every line item EXCEPT the one you want to delete.  Then update SAP.
private void DeleteLineFromOrder(string itemCode, string projectCode)
            // Load SAP order via B1WS
            string sessionID = B1WSLogin();
            GetSAPOrder(docEntry, sessionID, out _order, out _document);
            int oldLineItemCount = _document.DocumentLines.Count();
            // Create collection of the current lineitems, before the add.
            DocumentDocumentLine[] originalLineItems = _document.DocumentLines;
            // Update the line item count
            _document.DocumentLines = new DocumentDocumentLine[oldLineItemCount - 1];
            int lineItemCounter = 0;
            foreach (DocumentDocumentLine originalLineItem in originalLineItems)
                if ((originalLineItem.ItemCode != itemCode) || (originalLineItem.ProjectCode != projectCode))
                    originalLineItem.LineNum = lineItemCounter;
                    _document.DocumentLines.SetValue(originalLineItem, lineItemCounter);
                    lineItemCounter++;
            _order.Update(_document);

Mike
