Hi Uwe, the reason for having "global" uniqueness on category options is to simplify synchronization between systems and for uniformity between DHIS objects (codes are unique across all "identifiable objects"). I agree that it could be convenient to have uniqueness-within-category. That also provides some complexity when synchronizing meta-data between DHIS systems.
In any case, the idea is that you should re-use category options between categories. The benefit here is improved analytics - you can now analyse data for a category option across categories in pivot tables etc. So as an example, if you have a single "Female" category option in the system, you can now do analysis across all data elements (with different category combinations) that uses this option. regards, Lars On Mon, Nov 30, 2015 at 6:03 PM, Bob Jolliffe <bobjolli...@gmail.com> wrote: > Uwe you are correct in your discovery regarding uniqueness. > > There is a bit of history to the problem which I can't go into all the > details here.
