Issue with common distribution channel

Hi

We have two distribution channels 01 & 02 for sales org AU00. I created a material in AU00/01.

I configured the Common distribution channel as below, so I don't have to extend the material into AU00/02.

AU00 - 01 - 01

AU00 - 02 - 01.

However, when I create a sales order with this customer (AU00/02) & material maintained in AU00/01, I get the message that the material is not maintained in AU00/01. Have I missed anything in the config?

The requirement is to able to maintain the material in one distribution channel and able to sell it in multiple distribution channels without having to extend the materials. How can I achieve this?

Thanks
