SDP - planning book selection

Hi gurus,

I'm new with APO and trying to customize Best Practice according to ConfigGuide. i have a clean system. i've completed to configure macroses for my new own planning book. now I should go to SDP and select my own planning book on the selection screen. but when i run /n/SAPAPO/SDP94 the selection fields are gray and i get a message 'No valid version exists for planning area '9ADP01' Do you want to initialize a planning version?'

there is nothing about creating anything for this planning area in the configguide. if i select 'no' i see planning book '9ADP_BASIC' that is empty.

could you please help me to select my own planning book?

thanks a lot.
