In BeX only Key is display instead of Text in filter value

Hi,

Our company migrated from BW 3.0b to BI 7.0 Netweaver 2004s recently.

Before the migration, a value in the Filtersection of an executed query in the BEx Analyzer was displayed as text. Now after the migration it always displays the key instead of text.

If i put the same InfoObject in the Free Characteristics than it shows text like i choosed in the display section of the properties.

Do you have any clue why?

Thanks

Ralph
