How to access relations view in the sales order graph from another graph - 2022 R2

Hi @Lalith ,
Could you please try below code snippet to insert data in Relations Tab?

 #region Relation: Opportunity -> Sales order

            var relationExt = docgraph.GetExtension<SOOrderEntry_CRRelationDetailsExt>();

            var opportunity = (CROpportunity)PXSelectReadonly<CROpportunity, 
                  Where<CROpportunity.opportunityID, 
                  Equal<Current<Document.opportunityID>>>>.Select(Base);
                     var relation = relationExt.Relations.Insert();

            relation.RefNoteID = salesOrder.NoteID;
            relation.RefEntityType = salesOrder.GetType().FullName;
            relation.Role = CRRoleTypeList.Source;
            relation.TargetType = CRTargetEntityType.CROpportunity;
            relation.TargetNoteID = opportunity.NoteID;
            relation.DocNoteID = opportunity.NoteID;
            relation.EntityID = opportunity.BAccountID;
            relation.ContactID = opportunity.ContactID;

            relationExt.Relations.Update(relation);

#endregion

Hope, it helps!
