How to set up two way relationships in lists with lookup


I am trying to connect two list via lockup. Basically one is showing the company and one the contacts.
Setting this up one way is easy... What I want to do is that, when I add a contact with the lookup company as one of the fields -> then automatically the contacts column in the Company table should also show this contact and the link to it.

If tried several ways, but I can't get it to work in Power Automate. Is there a guide on how to do this?

I have also found an old guide that you can do this with list relationships, but the option seems to be gone in the current sharepoint version.

Thanks for your help!

Hi @Michael_Anton_F,


As an alternative I would recommend using Microsoft Dataverse for this type of data. It is honestly a bit better at relational data and the account and contact are out-of-the-box tables.


I don't know if Microsoft Dataverse is available in your environment? If so, it might be an option for you?


Thanks for the idea, I will check it out, but for now I need to use Lists. And there must be an option, I am either to dumb to find where they moved the button or it's called something else now. I can't imagine that this functionality has been removed.
