Match the webshops/markets in your ERP with markets in Geins yourself.
Each row connects:
a Webshop/Market ID from your ERP, and
a Geins Market.
Good to know
Type each ID exactly as your ERP sends it – same spelling and same upper/lower case. A value that doesn't match is skipped without an error, and the default is used instead.
The Geins markets come from your Geins. If the list is empty, check that Geins is connected. An empty list almost always means the connection, not the setting.
This is shown when Map article to multiple markets is set to Yes and Field to map webshop/markets to Geins is set to None (use custom map).
