Characteristic Variables not showing in BEx

Hello,

I have created a whole bunch of characteristic variables in BEx, but the new variables based on characteristic navigational attributes are not appearing in BEx in the characteristic tree. All other variables appear OK.

These characteristic variables do exist in BW (I can't create another new variable with the same technical name as an already existing 'missing' variable), but they just don't show in BEx.

(We are running BW V310 Level 14).

Any ideas anyone please??

Thanks in advance,

Peter.
