customized setting for corrected history Key figure

HI,

I have a scenario where in i have to do manual correction to history KF.

one solution is copying the original history into corrected history KF using a macro and taking the corected history as the base and apply manual as well as automatic corrections..

Another solution is, the option in univariate forecast profile i.e

Read corrected history data from planning version.

Before checking the check box for the above field, we need to assign the new corrected history KF to forecast KF in the customizing of Demand planning.(this is as per SAP HELP documentation)..

But i did not find any thing related to this setting in demand planning customization in IMG..

where exactly is the place for the above setting..

Thanks for reading...
