BEX Query : unexpected values in tab rows.

Hi experts,

I work on BW 3.5, and have the following problem :

I have a web template with 2 tabs givings some result numbers. It works quite well on the validation environment.

I load it in production environment, and the following happens :

some results are incorrectly displayed. For instance, a ratio is displayed '125,12' (%), but when I ask for 'ratio definition' (right clic on the mouse), it gives me the right value (10,2 %).

How can it be ?

Is it a referenced SAP bug ?

Can it be arranged ?

much thanks to all contributors.

Fred
