How do I get an Opto11 R18 in the flat version?

Today, iWiCatalog does not export Opto11 catalogs in R18 version. You have to get closer to Eyes-Road which do translations from ebXML to Flat.

What is a public or non-public product ?

In iWiCatalog, the concept of public allows to indicate that the product is available for all opticians using your catalog. Non-public products are generally private label products that have no correspondence with a public version.

The catalog is set up in public or public and Groupment, the product will be present.

The catalogue is set up in Groupment products so any product, public or not, not attributed to the latter will not be present in the catalogue. Only the products attributed to the Groupment will be exported.
