Decision on the Staging layer and RRI

Question

Dear Experts,
i have scenario where in i have 30 characterstics out of which four are key and 15 key figures. which i have modeled in a cube and this cube in turn will get data from four levels of DSO's, and as per the business requirement out of the 30 characterstics 10 characterstics   keep changing thei value which is okay if they are in DSO but when the record comes to CUBE as per its standard functionality its retaining the history of chagnes and showing it in  the report. but the user want to see only the current transaction.
i have thought of three  methods which i can think of now which i am giving below:-
1.I am thinking of removing the characterstics that keep on change from the infocube and only keep them in the DSO and later create one report on Infocube and  which will give the characterstics and keyfigures (here the characterstics which don' t change) and  create another report on the DSO with the characterstics which keep on change and do a RRI so that if the user want to see the other charcterstics then he will do the drill down reporting and see his details...
2. Have a full load to cube  from the final DSO  so it will always bring the current transaction record to cube and the report will show only one record. but i think this is not sustainable in the long run as this will hamper the loading performance becoz the records will keep on increasing
3. Reporting on ODS this will also have its own performance problems
Plese kindly suggest me whether the third one is the right practice and will that have good performance results in data loading and report wise as well.
thanks and regards

Hi Edwin,
I am fine thank you and hope the same with you.
Actually i am having transaction data coming from PLM -Cprojects
in my transaction data for eg:-
Project ID, Project Status, Remarks, Finish date, Start Date, Variance, Float
100001, Released, XXXXXXX, 10-07-07, 01-07-07, 9, 0
here the project id, project status, remarks are characterstics and others are key figures
in my scenario except the project id other two characterstics keep changing like now the project status is released but later it may change it to Completed or canceled or Rejected and basing on the status the remarks will change and this field in the source system is a text which will be entered by the managers for some comments and (like this i have around 15 characters which change and these are all Zfields enhanced in the source system) and in the report they don't want to see the history they only want the current text or details entered by them but if i keep them in the cube i will be getting all the details right from the first record to the latest changes as the cube will consider all the chars as keys.
so what i am thinking is instead of keeping them in the cube i will keep these changing chars in the DSO and the unchanging or stable chars in the cube so if they want the details of the changing chars they will do the drill down reporting instead of me doing the full load to cube.
so i am thinking of making a drill donw reporting.
any ideas please.

Neel
