So I have a situation in H3 where the onboard samper takes a sample of fish and prawn sometimes from the same haul. The fishing is done with "2 bags" one for fish and one for prawn. These are sepparate Species selections with diffrent species lists. Now the unique key fields in SS are SScatchFraction , SSobservationType and SSobservationActivityType Hence I have no good way to have 2 SS fields. One way I can make things work is to make 2 seperate Fishing Operations by adding a separate FOsequenceNumber for each of the "2 bags" but is this the best way to do it? Or woud it be useful to have an Unique key of SSspeciesListName on the SS table as well? It is possible that several sets of species are selected from one catch.
