The "Organisation unit merge" function

Dear Experts

From version 2.21 the “Organisation unit merge” function are discontinued. In some context this was very useful. Can it be added back again?

Or I have to write SQL query to manually merge that.

Hi Hannan,

There were issues with the implementation in DHIS2, and it could have caused major havoc with the data, depending on the situation, thus there was a decision to remove this for now. I think the devs are working on a more permanent fix, but in the time being, I created two Postgresql functions (if you are using MySQL…these will not work).

The first, is to delete sites with data.

https://github.com/dhis2/dhis2-utils/blob/master/resources/sql/delete_site_with_data.sql

and then to merge them (which depends on the first function)

https://github.com/dhis2/dhis2-utils/blob/master/resources/sql/merge_orgunits.sql

Absolutely no warranty on this, so be sure to test very thoroughly your self! The merge function accepts different strategies (MIN, MAX, SUM, AVG, LATEST, FIRST) for numeric data. Non-aggregatable data (option sets, text, etc) will use the “latest” data in case of conflicts. You can of course tweak this to your needs.

Good luck!

Regards,

Jason

Dear Jason

Than you for quick feedback.

I already have a try with your functions and faced some issues earlier. I identified the issues and will tray again.

Hi Hannan,
I realized that I had committed an earlier version of this script. Please update again from the repo and try again.

If you have issues with the functions let me know, as we would like them to be generally useful, so if something is missing let me know. Hopefully, they can serve as the blueprint for the permanent fix in DHIS2.

Regards,

Jason
