Customer Exit default values

Hi Friends,

Need help.

Created Analysis Workspace for OLAP. Source is BEx query.

Bex query variable designed using customer exit for calendar week. (Default is last week)

When I created workspace in dev environement, last week default values (201323) came. every thing was fine.

Today we moved workspace from dev to Q.

I executed workspace, it is still showing 201323. But it has to show 201324.

Please help me.

Any workaround is there.

Am I doing some thing wrong.

Thanks,

Raj
