Distribution point does not support communication type RML

Dear All,

I am trying to distribute a document in SAP inbox. Communication type is RML and entered recepient as user name.

But system is giving error distribution pointdoes not support communication type RML.

Error message is

"Distribution point does not support communication type RML

Message no. 25226

Diagnosis

You have entered a distribution type that is used to distribute to a

distribution point. The distribution point that has been determined

does not support the communication type that has been entered in

Customizing for this distribution type.

Procedure

For this distribution point, maintain a default communication address

for the communication type in question."

What could be the reason for above message. I maintained communication type for particular distribution point.

Regards

Abhijit
