How to modify PDF print template in Portal..

Hi,

we are running BI and Portal (NW 7.0, SP14).

In the portal we enables the BI queries printing in PDF, but as far we use standard web template.

Now i copied the web template and want to add new Fields to the PDF document, such as like Query Name, User, System and customer Logo.

I was able to add web text items with the required field to the customer web template, but i was not able to see these fields when printing the document...

Please provide me with step for step describtion on how to add new fields to the PDF export or how should i proceed...??

Many Thanks,

Nazih
