the sample shows me the message "Unable to progress the report action..."
I want to call the data that is needed and what is the structure used to call that data.
by the way I would like to know which is the structure of the api used in the framework to solve the problem and call it in the report designer if is the same structure, unless it is not, I would make the threat in the right control post.
