Distribution Channel warning message creating an Interaction Record

Hello Community.

We have an issue while creating an Interaction Record in SAP CRM 7.0 SP11.  When creating other Business Transactions, the Sales Organization pop up window opens directly in order to select the proper channel but, in the case of an interaction record, it does not.  Instead it shows a warning requesting the distribution channel.  Once you click on the warning link, then the Sales Organization pop up window opens as expected.

Could you help us in explaining why this behavior is different from the interaction record and any other business transaction?  And, is it possible to avoid the warning and open the Sales Organization pop up window directly as it works in the others?

Here you can see what happens when you create a new opportunity, and the comparison with an interaction record:

Thanks for your help!
