Hide unit of measure in case of using selections in BEx Query

Hi experts,

we ware using BEx Query selection to display a key figure in a Time structure.

- Time structure (Columns): selection with fiscal year/period variable

- Key Figure structure (Rows): selection of the relevant characteristics and key figure

Now we want to hide the unit of measures each cell. Instead of that, we would like to display the unit of measure once in the first row or the description of the key figure.

Any ideas or experiences?

Many thanks in advance!

Best regards,

Michael
