This is my scenario:
Init + delta -
> CUBE A
ODS A -
> ODS B----
> ODS C----
Delta has been initialized and is flowing every nite from the ODS A into the three Datatargets shown above(via the PSA).
Now there is a defect in the update rule of ODS A to ODS C and i have to change the update mode of all KF to addition(it was overwrite before).
I have my entire data loaded to ODS C through Overwrite mode.Now if i change the update rule to Addition,how my next delta will work and how the records will be reflected in the ODS C and further to CUBE C?
Can anyone tell me the exact proces ?
thnks in advance
