break /outline problem

Hi all,

I work with Webi SBOP 4.0 SP2 Patch 17.

I have a table that contains customer group, customer number and value of sales.

On this table there is a break on customer group with footer with subtotal.

If in customer group there is only 1 customer and

if I restrict the customer with outline for this group,

the report does not display any rows as I would expect to see with a subtotal.

Before restrict

After

This happens only if in the customer group there is 1 customer code, in other cases is correctly displays the subtotal.

Can anyone help me?

Thanks

Simone
