Hello Fabiano,

the subreport element has a list of return values. You can bind the variables from the subreport to the variables in the main report and then use them in the main report. The variable can be null because if it was used before the subreport calculations take place. So if you're using a variable from subreport in a text field and you see null there, make sure that variable has a proper Evaluation Time option. Now means it will be evaluated as soon as it is encountered in a report. If that is before the subreport is executed then you need to delay the evaluation and put Evaluation Time to Report for example.
