Workbook in BW is seen only by the author !!!

Hi everybody,

I created a woorkbook in Bex with two queries inside it. If I enter to the BEx I can choose the Workbook from "My Favorites" and I can execute it.

But, if other BW user enter to the BEx, he can not see the Workbook! Why does any user see my Workbook?

For example, if I create any query, currently any user can see my query. What do I need to do to my workbook for other users can execute it?

Thanks and regards
