I have a question regarding the material forecastig view (MM02) in SAP ECC 6.0. When executing the forecast, there is the possibility to copy the historical values into the forecast values. However, this option is greyed out, so after a long search in debugging I've found out that only when the period indicator is T (day) this option is available. My question is: Why should it be greyed out when the period indicator is any different (eg Month)?
I searched a lot on the internet and in SAP help but I've found no answer.
Thanks a lot
