Generic & Variants - Maximum number of Variants

Dear folks

I am trying to create more than 999 variant in SAP FMS (Fashion for Retail).

However the error the following error occurs

Maximum number of values (999) exceeded for characteristic 'COULEUR'

Message no. CL192

I checked in CT04 and in the characteristics profile and i cannot see any point to influence this even though it is stated in the error message :

Change the setup of your classification system so that the maximum number is not exceeded.
