Re: Sales Assistant in Opportunity is Not working

1.  Created ZOPSM and assigned  'opportunity sales assistant' to ZOPSM.

in web UI all activities are displayed irrespective of what sales stage I select. Instead, how can I make these activities  dependent on sales stages?. based on what sales stages I select dependent activities should be displayed. 

2. Any idea so as to why 'opportunity sales assistant' won't work with ZOPPT?.

Thanks
