Dear Experts ,
In APO we have option in ADVM where certain KF can be set to non editable in future periods in any Planning View /Data View.
how same can be achieved in IBP Planning view where certain KF should not be editable for say first 3 months of future ?
as of now i can see only options as Editable in past, editable in current and future or so. but not for any user specific period .
ex.
