To make application have a dynamic filter on date

Hi all

I have data thats being snapshoted every week. The application should show current week and 8 weeks back dynamicly.

For that purpose we have created a USEREXIT variable, and placed it in the default section in the BEX query.

When using this BEX-query for the first time in DesignStudio, everything seems ok. The daterange filters the data perfectly, when viewing the application from BI Launchpad. The range is ex 01.2014 - 08.2014. Im using a Dimensionfilter in the application for the dimension CCALWEEK,

BUT when viewing the data the NEXT week, the daterange filter hasnt changed. I want it to automaticly become 02.2014 - 09.2014.

It works perfectly in BEXanalyzer, so it seems like the problem lies in DesignStudio.

We are running DS 1.2

Isnt this supported? It cant be a Designflaw
