Hi, I have an another question. I have a dataset that model entity like gene and a dataset that model interaction (between two genes) In my main table of interaction dataset, i have the fields gene1 and gene2. This two fields links the gene dataset on gene_key. How martview handle that there is two links between the same datasets?
