Can I add pv! data to a task report?

Hello,

I am trying to add pv! data to a task report but it always comes out empty. 

My data definition is: pv!record[W1182 Solicitud.idCategoria]

formatting: number 

It does not display any information. All information I request using tp! works fine. 

Am I doing it wrong? or is it not possible to display rv! info in the report?

Thank you
