Hello,
You'll need to enter 'selection id' or 'selection', and then enter 'group by', in order that you can get table 'characteristics_combination' filled. Even if you want to display values for all CVCs, you'll have to enter an selection condition 9AVERSION = 000 and a characteristic in 'group by'.
Please go to transaction 'BAPI' to check the documentation of this BAPI.
Best Regards,
Ada
