Cuterris,
This makes sense...what you are missing in the infocube YTIC1 is SAP dleivered characteristic 9AVERSION. Please add this to your cube. Probably you will have to delete the contents, add 9AVERSION and set it to constant value= 000. Load the cube and then you should be OK. I am sure you have initialized/created time series for yor Planning Area for Version 000.
Thanks,
Subash
