In my main report first data is coming from a json data adapter and other data i coming from a postgers jdbc data adapter.
like textfield 1 use json data adapter &
textfield 2 use postgres data adapter
so how can i mearge these two textfield in my main report together
you probably would need to use the json data in the main report and create a table element with the columns from your postgres
and pass the joining fields into the table dataset as a parameter to filter the data.
