InfoObject Assignment in Transfer Rules for Characteristic with Compounding

Hello,

We have 0CUSTOMER InfoObject that has master data attribute of 0REGION, which in turn is Compounded with 0COUNTRY. When providing Rule Details for mapping from DSO to InfoCube, the 0REGION value is read from Master Data Attibute rule type and 0CUSTOMER is assinged under InfoObject Assgnmnt colum. However, do I also need to inlcude 0COUNTRY in the Rule Details as part of Source field since 0Region is compounded with it, and if so, do I also need to provide 0COUNTRY under InfoObject Assignment column for this compounded characteristic field? I hope I have not made it look more difficult of a question than it really is.

Thanks.
