unable to display data in AX 2012 SSRS report


I need to duplicate a report in AX 2012, I have created a new project in VS and i have used the same Datasource and RDP class and manually copied and pasted the existing report design in new report design. In output its only showing the header and the first two labels and the rest of the data in not displayed.

how to debug it and can anybody suggest me what is the problem with my report.

Thanks in advance.
