Use as a model the following code in java.

Copy it into /home/openbravo/OpenbravoERP/AppsOpenbravo/src/org/openbravo/erpReports

In your .jrxml file you get the parameter C_ORDER_ID from the .java writing your SQL so:

SELECT DOCUMENTNO FROM C_ORDER_ID WHERE C_ORDER_ID=$P{C_ORDER_ID}

Copy your jasper template (.jrxml file) into /home/openbravo/OpenbravoERP/AppsOpenbravo/src/org/openbravo/erpReports

Then compile the changes using:

ant compile.development -Dtab=xxx

Now, you should change the current process that the print button from (i.e.) Sales Order windows executes. Go to Windows, Tab and Fields. Then look for the windows Sales Order and in the Header tab, locate the Process field. Change the value for your newly created RptC_Tiquet.

Then, compile the windows

ant compile.development -Dtab="Sales Order"

If you want to see your changes, restart apache-tomcat.
