No appplied measure aggregate and used raw value

HI,
I've got a raw value in my jsonData like :
{
"Color": "red",
"Destination": "Australia",
"Quantity": 58,
"Discount": 59,
"JP": "<a href='www.google.fr'>Test </a>"
}
I would like to show raw value for JP measure and no applied aggregate.
Is it possible ?
Important : In my example, the JP value is very simple but lots of parameters must be generated in server side to create the good href link, and it's not possible to generate it in client side.
Thanks for your help.
Julien
