@michoel I checked by loading an item record and then looked for the costingmethod .. unfortunately it isn't part of what gets returned. It only returns the costingMethodDisplay, so appears I'm back to square one. Because the costingMethod field becomes read-only when set, it is not returned in get and basic search operations. Instead, the read-only field costingMethodDisplay is returned. The costingMethod field can be used only for addRecord operations and in searches.
