If your ERP has several webshops or markets, enter the name of the attribute that tells which Geins markets an article belongs to.
The attribute's value should be a comma separated list of market IDs, Channel IDs or names. Which of these you use is set in Field to map webshop/markets to Geins.
Good to know
For example, an attribute with the value
1,3would put the article in the markets with ID 1 and 3, if you map by ID.This is shown when Map article to multiple markets is set to Yes.
