Display method through filtering

I want to display the allocated Develoment Officer from the smmResponsibilitiesEmplTable on the SalesQuotationTable form

SalesQuotationTable.OpportunityId == smmOpportunityTable.OpportunityId

smmOpportunityTable.RecId == smmResponsibilitiesEmplTable.RefRecId

smmResponsibilitiesEmplTable.ResponsibilityId == “Development Officer”

return smmResponsibilitiesEmplTable.EmplId

Is this possible through a diplay method ?
