Project description
Greetings!
I am interested in the person who has correctly linked this case.
What exactly is the problem:
We have 2 IB. Catalogue and bid bid.
Example:
Product itself: iPhone 6 16
And he's haggling. Proposals
iPhone 6 16 Gb Gold
iPhone 6 16 Gb Silver
iPhone 6 16 Gb Space Gray
Therefore, it is important for us to change the price and available amount only at the auction. Suggestions. The structure of our products is exactly that.
My Warehouse (hereinafter MS) links goods to the store by external code (id) and looks at categories in the same way. I mean. The structure and external codes should be exactly the same as on the site.
When synchronized, he doesn't find a bargain. The offer (apparently does not take into account the infoblock) and creates a new product in the catalog.
What we need:
Everything is synchronized with the site and vice versa. If there is a sku, then when updating they got into the sku information security and did not create new products (and did not change the type of goods).
Preferring someone who has already done this. We can't give up SKU, so we need to find a solution.
