APO DP - loading characteristic value combinations to a worklist

I am using APO DP V5.

I am using transaction /SAPAPO/MC62 to create characteristic combinations via loading to a worklist.

I am using an InfoCube as my 'data source'.

I know that in the Cube there are 9 combinations, and if I select 'Number of Hits', system returns correctly with answer of 9.

But if now hit Execute, system returns message /SAPAPO/TSM297 with text 'No combinations found'.

Any ideas?

Thanks, Bob Austin
