How Can I Create Related Fields in the SalesLogix Application Architect?

Question: How can I create Related Fields in the SalesLogix Application Architect?  I need to related two entities – Opportunity and OpportunityAssociation – in this way:
 
OpportunityAssociation.ChildOpportunityId is related to Opportunity.OpportunityId
OpportunityAssociation.ParentOpportunityId is related to Opportunity.OpportunityId
 
Answer: To do this you will want to right-click under one of the entities and choose add a new relationship.  Next, select the right tables, right fields, and right direction – 1:M from Opportunity to OpportunityAssociation.  Then, in the OpportunityAssociation table you will call the relationship “Opportunity”.  Finally, in the Oppportuity table, you will call the relationship “OpportunityAssociations”.
