Copying information from one table to another in Arena OF (Select distinct)

Question

Hello everyone, I have a need in Arena OF, which I don't think is currently possible, but I'd like to ask if anyone has a good idea. We want to use Arena OF to collect data from a shrubland inventory in California for carbon estimation. The field methodology we are considering is line intercept transects. For each one-meter section, we will collect cover and height (in four classes) by species. So, we will have a table with Transect_ID, Section_ID, Species, Cover, and HeightClass. At the end of the transect, we want to individually measure a "typical" individual of each species and height class in each transect. Ideally, using the transect table, I would do a SELECT DISTINCT and create new records in a new table of individuals. Any ideas? Thank you so much as always!! Oscar

Dear Oscar, At the moment we don't have such a feature in Arena. What you could do is just create a new entity with an attribute "species" as key, and a validation rule that checks if that species has been inserted in the items of the previous entity (called "section" for example), with an expression like this: count(section[section_species == this]) > 0 Please let us know if you need further assistance from our side. Many thanks, Open Foris Team
