BW transport - variable prompt not transportable?

Dears,

I do have  a Bex Query in my Workbook with a User prompt. I created a variant in the Excel Workbook on a set of company codes and saved it as "global". How could I transport in BW this global variant. Once i transport the workbook from development to production It does not transport the variable. Even if i transport all related objects in the Datawarehous Workbench - transport connection.

Thanks for your support.

Cheers,

Felix
