Collection datatype disabled

errorrelativo Member Posts: 12 Blue Ribbon


I'm a newbie (a 50 years old one) who recently started to try Data Modeler.

I'm trying to replicate a Logical Model in which one attribute is multivalued.

The language in which I'm using Data Modeler is Spanish and I see that there exists a datatype called Recopilación (together with Dominio, Lógico, Distinto, Estructurado), which I think corresponds with Collection in English, and should be the type I could use for a multvalued attribute.

Unfortunately, Collection is disabled (as well as Distinct) and I have no idea how to unable it. I've been searching on the web but have found nothing.

Could someone help me?

Thanks in advance.
