Hi Seid and Andrei,

Currently this feature is planned for 2.28 of DHIS2. If you use Jira to follow the DHIS2 features, it is outlined here: https://jira.dhis2.org/browse/DHIS2-66 <https://jira.dhis2.org/browse/DHIS2-66>

Currently none of the aggregation operators support this. The Average (sum in orguinit hierarchy), Minimum and Maximum are closer but none of them are satisfactory since the number of patients who are currently on ART may increase or decrease in the specified time span.

Reading the documentation I assume there is not LATEST relative period, and currently we have to do the following to get the desired result:

> orgUnitGroup -> child1, child2
