You only need 952$y. 942 is a fallback because all items need an phenotype, but in the past it was not enforced, specially on import.

I am wondering if it is necessary to have both the 942$c field and the 952$y field in the framework as they seem to record the same information i.e Koha item type. Is there an advantage to recording the same information in both fields and if not which is the preferred? We are using Koha 3.22 thanks!
