Hi @Pacifique_Hategekima
The usual approach here would be to have two seperate data elements and data sets…one for results and the other for targets. You would then need two seperate user groups, one for users who can edit targets, and another for users who can edit the results data. I assume that users in both groups would be allowed to view both targets and results.
Using the sharing functionality of DHIS2, you could then share all of the data elements and the dataset which are related to results with the user group who should be able to edit them. You would then do the same for the targets data elements and data sets.
Hope this helps to explain. If you have additional questions, please feel free to follow up.
Regards,
Jason
