No Adpater Engine available in Communication Channel creation

Hi,

In Configuration, I Assign my new <i>Business System</i> Object in <i>Service Without Party</i>. After, I try to create a <i>Communication Channel</i>. Whatever the type of my <i>Adapter</i> (ex: File or RFC) and whatever the <i>Software Component Version</i> (ex: 6.40 or 7.0), <b>I never have an Adapter Engine</b> choice in the list box, it is always blank.

What should I do to complete my <i>Communication Channel</i> creation?
