Cancel salesline through code

The code is based on the logic in the form SalesUpdateRemain ("Deliver remainder" button in the sales order header).

static void cancelSalesLine(Args _args)
{
    boolean updated;
    SalesLine salesLine; 
    
    try
    {
        ttsBegin;        
        
        salesLine = SalesLine::findInventTransId('012411', true);
    
        updated = SalesUpdateRemain::updateDeliveryRemainder(salesLine, 0, 0);
    
        if(updated)
        {
            info("Salesline canceled");    
        }        
        
        ttsCommit;
    }
    catch
    {
        error("SalesLine could not be canceled");
    }
}
