BEx 7.0 : WorkBook protection & warning messages

Hello everyone,

I've got a workbook I protected with a password through BEx analyzer's option "Workbook Settings".

However, when I open it again, I get this warning which pops up even if the option "Display messages automatically" is not enabled : "Worksheet BExRepositorySheet is protected without supplying password".

The point is that I don't want this warning to be displayed or, if possible, I would like to suppress it. How can I get rid of it ? Finally, I don't even understand where this warning comes from...

Regards,

André
