How to import the products into the existing group

When you select Import group, you can import groups that already exist in the system. You only need to select "If the group already exists, add items to the group".

Import group to exist group

If the product already exists in any group, it will not be imported into the corresponding group.

If you do not check this option, the group products you configured in the import file will be ignored and will not be imported into the group.
