Not sure if your question is clear enough, but seems you wanted to have data collected at lower levels (Regions) be aggregated to higher level (Ethiopia).
One approach you can handle this is:
collect your data at lower level (first make sure your data elements have the aggregation type you need)
run analytics
go to pivot table, select the data elements and indicators you want to see and click update. the system will automatically handle the aggregation.
If you want to have a report with a specific layout, logos and related items, you might need to consider custom jasper reports. See here fore more info.
