Hey Martin, I suggest that you use (if necessary create) an organisation unit group set-based dimension in your request. The group in question needs to be part of the group set. In this case we can use the org unit group set called "facility type" as an example, where CHC is one of the groups.
Facility type - org unit group set - id: J5jldMd8OHv CHC - org unit group - id: J5jldMd8OHv:CXw2yu5fodb Now this group set dimension can be used as a filter. In your example above, the API correctly returns a message explaining that a single dimension cannot be used as both dimension and filter. We now have this URL which I think gives you what you want: https://play.dhis2.org/demo/api/analytics.json?dimension=dx:fbfJHSPpUQD&dimension=pe:LAST_12_MONTHS&dimension=ou:ImspTQPwCqd *&filter=J5jldMd8OHv:CXw2yu5fodb* best, Lars On Fri, Jan 20, 2017 at 4:15 PM, Martin Van Aken <mar...@joyouscoding.com> wrote: > Hello everyone, > I've a question on the analytics API.
