DHIS2 - Data Visutalization/Reports

I am getting No Values found while trying to configure report/charts in DHIS2.

I have been

1. Created DataElements
2. Created Category Options
3. Added a Category to include Category Options
4. Created a Category Combination item to and added the category created in Step3 in it.
5. Now updated the DataElements and assigned the Category Combination.
6. Now created a DataSet with these DataElements and assigned to the 2. organization units.
7. Using the DataEntry module the data is added successfully for desired time period and marked as completed.

But when trying to create a report/chart for these DataElments or DataSets, I am getting the message that No Values found. However when trying to create reports/charts on Demo site, everything works fine.

Is there anything that I am missing where while performing all the above mentioned steps.

Thanks.

To use the stored values of completed data sets, once must run Analytics.

See the image below for reference.

First Click on Analytics and Data Mart Second click on the Start export with Analytics tables update check box marked.
