This article is an attempt on how to store the reference of an article as an attribute of the ticket line, to print on the receipt.

Implementation

The method is:

• You must create a new ticket addline event. So you must edit Ticket.Buttons resource and add this line in the <configuration> section:

 
<event key="ticket.addline" code="event.addline"/>

• Then you must create a new resource called event.addline with this content:

 
// Add product reference to a ticket line, y in the line is a product (discounts and others have no reference).
 
import com.openbravo.pos.forms.DataLogicSales; 
import com.openbravo.pos.ticket.ProductInfoExt; 
import com.openbravo.data.loader.Session;
import com.openbravo.pos.ticket.TicketLineInfo;
 
Session session = new Session(database_url,  database_user, database_password); 
DataLogicSales logic = new DataLogicSales();
logic.init(session);
 
try {
	ProductInfoExt product = logic.getProductInfo(line.getProductID());
	line.setProperty("product.reference", product.getReference());
} catch (Exception e) {
	line.setProperty("product.reference", " ");
}

In this scriptlet you must replace database_url, database_user and database_password by their corresponding values.

• Now all lines will have reference as an attribute: product.reference. If you want to print it in your ticket receipt,then you must edit Printer.Ticket resource (or what you use), and add this where you want ('in line section'):

 
${ticketline.getProperty("product.reference", "")}

Example

 
        <line>
             <text>----------------------------------------</text>
        </line>   
        #foreach ($ticketline in $ticket.getLines())
        <line>
            #if ($ticketline.isProductCom()) 
                <text align ="left" length="10">*${ticketline.printName()}</text>
            #else
                <text align ="left" length="10">${ticketline.printName()}</text>
            #end
            <text align ="right" length="5">x${ticketline.printMultiply()}</text>
            <text align ="right" length="25">${ticketline.getProperty("product.reference", "")}</text>
        </line>   
        #if ($ticketline.productAttSetInstId)
        <line>
	        <text align ="left" length="40">    ${ticketline.productAttSetInstDesc}</text>
        </line>
        #end
        #end
        <line>
             <text>----------------------------------------</text>
        </line>
