Like with Entity, the members that you do not select will not be included in the corresponding Account dimension in CXO. A major difference is, however, that all the levels below a selected member will automatically be included in the extraction and the dimension build-up in the CXO-Cockpit application. So, even though we only selected 'NetProfit', within CXO we will include all details of the underlying members all the way down to the base-level:
Best practice is to avoid multiple occurrences of members in the selection. This will slow-down the Processing of the OLAP database and/or the report queries. In doing that you should always realize that we extract all details under a certain parent node: even if you did not select duplicate members they can be there implicitly among the descendants of selected nodes.
