You are a multi-brand reseller and the manufacturers impose brands or items display restrictions on different channels?
Your catalogue includes many product categories, but you aren't allowed to publish them all on a channel?
Focus on the products you have the right to display. Segment your catalogue before setting up the channel in Lengow.
How to do it?
Create a Segment
Create a Segment on the Catalogue you want to link the channel with.
You'll then exclude from this Segment, products you aren't allow to display on this channel.
Link this sub catalogue to the channel of your choice
When adding a channel in your account, select in the dropdown menu from the channel of your choice the Segment you want to launch.
This dropdown menu is only displayed for catalogue for which you have created a Segment.
Keep in mind that if the same restriction applies to multiple channels, you'll use the same Segment for each of them.
Set up the channel
Follow usual set up steps.
