Subreport isn't shown when exported to pdf, xls or doc

I have a main report and a subreport working nice. The subreport is printed in the su开发者_Python百科mmary band. My problem is when I export the report. The subreport is invisible, only main report is presented. I export to pdf, xls and doc. In all 3 formats is the same.

Are you export in your laptop?. if not. you must delete path folder in xml tab before.
