Hi @gregory
Thank you for your post and for sharing the use case with the community. I tried to do a research and tried to see if it’s possible by testing on play, but it seems that currently there’s not been a feature to restrict the number of relationships in a TEIs.
It appears that this is an idea that could be discussed more with the team. You have already started the discussion here which is very helpful, and I would like to recommend adding this as an idea - here’s the guide on how to create ideas: Vote for DHIS2 features & submit your ideas in our new software roadmap process!
After creating the idea, would you like to share the link here so other community members could vote for that idea if they need it in their implementations? Thanks for sharing your insights!
