Need help with Relationship Issue

I am having 2 tables case-data and Incident. The relationship between these two table is one to many i.e 1 service request can be associated with multiple problems hence multiple support tickets.

Case-data table has primary key as ServiceRequestNo

Incident Table has Foreign key as Support ID No

The problem is initially I see all the possible Service Requests but as soon as I add Support Ticket ID field to my report values it shows me only those service requests which have a support ticket.

In technical terms, this is more like an inner join whereas I want left join because incident table has team name and I want to filter by how many total cases came to a particular team.

Can someone help me how can I fix this?
