dynamic fields in notification email template

[dyabolik00]

Hello,
I have this issue.
I've create a custom notification base on a dynamic field status (dtstatus) that has multiple states: (active,inprogress,completed). This notification is triggered when the dynamic field change to completed and it send an email to the customer that open that process ticket.
The email arrive just fine and i'm using a custom template stored in /opt/otrs/Kernel/Output/HTML/Templates/Standard/NotificationEvent/Email/
I try everything to send via that email some dynamic field of that ticketprocess but i'm unambled to see them.
In my custom tt file i tried:
[% Ticket.DynamicField_Surname %]
[% Data.Ticket.DynamicField_Surname %]
[% Data.DynamicField_Surname %]
[% Data.Surname %]
[% Surname %]
[% Ticket.Surname %]
[% DynamicField_Surname %]
<OTRS_TICKET_DynamicField_Surname>
<OTRS_TICKET_DynamicField_Surname_Value>
<OTRS_TICKET_DynamicField_Surname>

None of that work . is there a way to do this? or how do i pass the dynamicfield for that email body?
I've looked at /opt/otrs/Kernel/System/Ticket/Event/NotificationEvent/Transport/Email.pm and i dont see any reference for dynamicfields.

In the notification templates are only Subject and Body set. Place your DynamicField into the notification.

You mean in the Email.pm file?
I found this:
# generate HTML
$Notification{Body} = $LayoutObject->Output(
TemplateFile => "NotificationEvent/Email/$EmailTemplate",
Data => {
TicketID => $Param{TicketID},
Body => $Notification{Body},
Subject => $Notification{Subject},
},
);

but i dont see any reference to dynamicfields in this file. I tried adding %Param, to data array but nothing . How can i add all dynamic field to this?

Use the DynamicField in the notification body with the proper tag.
