Format Evdre: DrillDown

Hi,

I use SAP BPC 7.5 MS.

I want create an evdre with drill & down functionality and I liked it looks like if I enable the default formatting range (child member appears with a different colour than the parent colour), but my customer don't want use the formatrange option.

I tryed to found how it works, but I do not found it.

Do you have any idea?

Thanks!
