Data reconciliation

Hi all,

i have APO cube ZAPODATA which was getting updated from standard dso zds_lo13

Cube having characteristics channel I.e. whole sale retail international retail which is getting calculated by data field of dso customer group

When customer group is 1 channel is wholesale

When customer group is 2 channel is rtl

When customer group is 3 or anything it's international retail

This calculation is carried out with the help of field level routine

Now we have change in requirement we want to adde

When customer group is 13 it's should be consider as wholesale

Now questions over here is how to correct the history' data without deleting previous one

Because in cube Channel data is already aggregated ??

Please help me in this asap
