Answer 1

You need to first get the document you want to alter using DocEntry.

You then have to set the line number that needs deletion. See below

Documents oDoc = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oOrders);
int docEntry = 109;
int lineNum = 2;

// Load your sales orders
if (oDoc.GetByKey(docEntry))
{
    // Go through your line items
    for (int i = 0; i < oDoc.Lines.Count; i++)
    {
        oDoc.Lines.SetCurrentLine(i);
        if (oDoc.Lines.LineNum == lineNum) //Find your line number that you want delete.
        {
            oDoc.Lines.Delete(); //Delete
            break;
        }
    }

    // Update your sales order
    if (oDoc.Update() != 0)
        MessageBox.Show(oCompany.GetLastErrorDescription());
}
