Looks like no transactions are available in your environment to show in MR report. That could be the reason of showing this on screen info.
Please check the following.
-- Financial reporting setup.
Make sure that you selected the combination in the same way as it is configured in both "Account structure" and "Financial dimension combination for integrating applications" forms.

-- Have a look in the row definition of the MR report and see which main accounts / account categories have been mapped.
-- Post few transactions based on those accounts.
-- Generate this report for the same time frame where you posted the transactions.
If still no result display in the report; then click on Tools > Refresh cached financial data and generate the report again.
If no luck yet, then go back to Tools > Reset data mart and see if this solves your case.
Once the status in reset data mart for all processes becomes "Ran to completion", then generate the report again.
