Hi @MELB
Thank you for raising this question with the community. It’s an important topic to be aware of. Would you please share the Jira issue so one could have a closer look at it with all the description and steps to reproduce?
Additionally, what version of DHIS2 are you using?
Please know that it’s important to differentiate between the latest apps and the legacy apps, (Event Report app and the Event Visualizer apps are old apps and are or will be replaced see here) Regardless of the legacy apps app, I would like to know if there’s a mismatch between the actual data and the Line Listing app?
First, it’s important to note that sometimes some of these issues could be because of misconfiguration or issues within the database itself and not the system. It’s always recommended to create back up of the data before upgrading as well as a couple of other instructions to ensure that the upgrade happens without a fail in any aspect. (Upgrading - DHIS2 Documentation)
Second, to the best of my knowledge, if there’s any software bug it’s usually noticeable and it doesn’t affect the raw data itself so once there’s a fix, everything returns to normal since the capture “input” apps are not the same as the visualizing “output” apps.
So as I understood from your post the issue is with the mismatch between the values in the different apps? I hope with the jira issue you share, we’ll have more insight into what issue you are facing.
Thank you!
