Change Display name of Managed Field in Dynamic 365

Sometime we need to change the Display name of Managed field in Dynamic 365.

The following code is used to change the Display name of Managed field.  

IOrganizationService orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

RetrieveAttributeRequest attributeRequest = new RetrieveAttributeRequest

                {

                    EntityLogicalName = Opportunity.EntityLogicalName,

                    LogicalName = "parentaccountid",

                    RetrieveAsIfPublished = true

                };

                // Execute the request

                RetrieveAttributeResponse attributeResponse =

                   (RetrieveAttributeResponse)orgService.Execute(attributeRequest);

                Console.WriteLine("Retrieved the attribute {0}.",

                   attributeResponse.AttributeMetadata.SchemaName);

                // Modify the retrieved attribute

                AttributeMetadata retrievedAttributeMetadata =

                   attributeResponse.AttributeMetadata;

                retrievedAttributeMetadata.DisplayName =

                   new Label("Bidding To", 1033);

                // Update an attribute retrieved via RetrieveAttributeRequest

                UpdateAttributeRequest updateRequest = new UpdateAttributeRequest

                {

                    Attribute = retrievedAttributeMetadata,

                   

                    EntityName = Opportunity.EntityLogicalName,

                    MergeLabels = false

                   

                };

                // Execute the request

                orgService.Execute(updateRequest);
