Replacing Old characteristic with new ones in a Cube

Question

Hi,
I have 3 Z InfoObjects for capturing time information like the month, year and week. The user is requesting for variables like current month, current year etc on these variables frequently. I have written customer exit for bringing the current week etc values on the Z InfoObjects.
However, I want to avoid writing of the code in future and hence have created 3 more InfoObjects which reference to the standard time characteristics, i.e. the Z month InfoObject will refer 0CALMONTH etc. so that the standard variables of 0CALMONTH can be used for our Z InfoObjects also. Now I want to replace the old InfoObjects with these new InfoObjects(the ones referencing the standard time characteristics) in a InfoCube. My question is how do we get the historic data for these new InfoObjects as the Historic data is in the old Z InfoObjects. Any thoughts/suggestions would be helpful..
thanks in advance.

<i>Generated export Datasource of the InfoCube after adding the new 3 characteristics. Then in the Update Rules mapped only these 3 characteristics with the old characteristics and did a full upload.</i>
You need to map the 3 old Characteristics to the 3 new ones, and you need to map all the other InfoObjects too.
In the following I refer to the 3 old temporal Charactersitcs as T1, T2 and T3 - and to the 3 new temporal Chars as T1', T2' and T3'. The other (old) Chars are referred to as Cn, and the Key Figures as KFn:
T1 --> T1'
T2 --> T2'
T3 --> T3'
C4 --> C4
C5 --> C5
KF1 --> KF1
KF2 --> KF2
After the load you should delete the old requests to avoid data duplication.
<i>I was expecting that the record will have the new characteristic and also the value in it after the load. But it is not happening.</i>
I reckon you don't have any value because you haven't mapped the Key Figs (as well as severlal Characteristics) in the Update Rules.
