We can associate the Competitor to the Product using the
below code.
var xrm = new XrmServiceContext("Xrm");
Guid competitorId
= new Guid();
EntityReferenceCollection relatedEntitiesCompetitor = new EntityReferenceCollection();
relatedEntitiesCompetitor.Add(new EntityReference(CompetitorProduct.EntityLogicalName,
competitorId));
Relationship relationshipCompetitor = new Relationship("competitorproduct_association");
xrm.Associate("product", newProduct.Id, relationshipCompetitor,
relatedEntitiesCompetitor);
Here the competitorproduct_association is the
relationship between the Price List and the Product. We can see the
relationship in the CRM portal. The steps are
Settings->Customizations->Customize the
System->Entities->Select the Entity ->Click on Relationship.
