The planned upgrade to DHIS2 2.29 has a known issue for site administration that we are currently working to resolve as soon as possible. The Organisational hierarchy within the Organisation Unit module of the Maintenance application is not functioning properly.
To workaround this issue, please use the Search bar above the organisational hierarchy to find the org unit that you wish to alter. Please note that the search has now been updated to also display the Parent unit of the org unit that you are searching for.
Please note that we have experienced some slowness while testing this app, so when navigating between org units or deleting org units, there may be a delay of several seconds.
We are working to resolve the organizational hierarchy issues as soon as possible, and appreciate your patience in this matter. If you have any questions or require an output of your org hierarchy to reference, please contact DATIM Support.
