Lookup from another column in same table

Hi. 

 

Appologies if this has been answered before, it's seems like it should be strait forward.

 

Is it possible to create a lookup column that references another column in the same table.

 

I manage an aquarium, I have multiple water systems and some of them are connected together as in system 1 supplies water to system 2. 

 

I have a table that lists all the systems and want a column, in that table that shows which other system supplies it.

 

Is that possible?

I have the same question (0)

    Hi @Paultys ,

     

    Dataverse allows user to create self-referential lookup field.

    Besides, we can define hierarchical data for the relationship.

    Best Regards,
