Delivery unit In Sales Documents SAP CRM

Hello Experts!

I have a doubt respect  the  delivery unit.

In SAP ECC when I capture a sales order at level position the system send a messsage with the next text (when the unit captured is lower than the delivery unit of the material master):

Consider delivery unit 4 EA in item 000010

I know the delivery unit is maintained in CRM transaction COMMPR01 -SALES AND DISTRIBUTION TAB-

But when I créate a sales document in CRM the system does not perform the message like ECC.

How can I actívate this customizing in SAP CRM for my sales documents?

I'll be very grateful with your suggestions.
