Automatic mapping
Trying to map every unmapped product in one pass.
What it does
It walks through your unmapped products, looks for a matching Odoo item by SKU, barcode or internal reference, and saves what it finds.
When to use it
After uploading a batch of new products, after correcting codes in Odoo, or during first setup of a large catalogue.
It leaves existing links alone
Already-linked products are untouched. Running it is safe and can be repeated without worry.
It is only as good as your codes
If your Zid codes do not match what is in Odoo, automatic mapping finds nothing. Fix the codes first, then run it.
Check the result
Afterwards open the Products screen with the Unmapped Only filter to see what is left, and map it by hand.
