I have a custom module. Some applications are loaded like Crm, Sales, Invoice vs...

There are two fields in lead form : Sales Person and Other Sales Person 

The other salesperson does not see the opportunities he has been assigned on My Pipeline.

I need to write a filter for it. Does anyone have an idea?

<record model="ir.actions.act_window" id="crm_lead_extended_opportunities">

            <field name="name">Extended Pipeline</field>

            <field name="res_model">crm.lead</field>

            <field name="view_mode">kanban,tree,graph,pivot,form,calendar</field>

            <field name="domain">[('user_id','=',x_other_ssales_person.id)]</field>

            ....

</record>
