Daily Prices have limitations when it comes to sending them to the channels. You and either send them or not send them but you can not control which channels you send them to. If you want to send different prices to different channels you need to use rates.
==Multiple rates for channels ==
Some channels support multiple rates for example refundable/non refundable, standard/last minute/early bird, prices for different occupancies. The capabilities depend on the channel and are explained on the help page for each channel.
Note:
The prices will only be sent to the channels you have activated in the channel manger settings.
