We are currently using DHIS2.31.3 Build 99d7b74
We have lots of datasets and use expiry date to block forms.
The interesting question is that the process of entering each dataset to block and difficult when you have many forms.
Is there a way to be able to close all datasets simultaneously using expiry date?
I hope you are well. Sorry for the late response to this; did you manage to sort this? This is possible via API though you have to be good at using API calls to your instance to avoid errors. I would still recommend you do this manually one by one as you will be sure of what datasets you are editing.
I will follow your recomendation
