Excel Pop-up

Hi,

In a particular report, i've got the following pop-up when opening the excel export:

(translation from french: "Name already used - Name can't be identical to a predefined name").

It seems that there is a problem with names generated automatically for cells references.

When I suppress report's header, the pop-up doesn't appear.

Any explanation for this behaviour ?

Thanks in advance.

Grgory.

I have the same problem !!
