Subchannels are channels located under a channel and they inherit all products of the parent channel. Subchannels don’t inherit channel settings or mappings. The main purpose of subchannels is to create feeds to eCommerce marketing and advertising platforms. They are also useful when you want to send feeds to your resellers. You can change any settings such as pricing, inventory masking, inclusion, availability settings, and description or tags.
Go to Menu > Settings > Channels.
>> Click on Plus sign “+” towards the right-hand side of the screen which is under Actions.
>> On the upcoming dialog box, you can see all sales platforms or providers; select one option and next, give your new channel a name and click create.
