After a few trials and errors, we created the relationship with the name in the format we wanted, and below are the steps to achieve it.<\/p>\n
Firstly, we need to add the IsCustomizable property to our LookupAttributeMetadata with the value a new BooleanManagedProperty with the value as true.<\/p>\n
\/\/ Create a new instance of BooleanManagedProperty\r\nBooleanManagedProperty boolManagedProperty = new Microsoft.Xrm.Sdk.BooleanManagedProperty();\r\n\r\nboolManagedProperty.Value = true;\r\n\r\ncreateMultilookupField.Parameters[\"Lookup\"] = new LookupAttributeMetadata()\r\n\r\n{\r\n\r\nSchemaName = fieldSchemaName,\r\n\r\nDisplayName = new Label(fieldDisplayName, languageCode),\r\n\r\nIsCustomizable = boolManagedProperty,\r\n\r\nDescription = new Label(description, languageCode)\r\n\r\n};<\/pre>\nAfter the change in LookupAttributeMetadata request, we need to add the ReferencingEntityNavigationPropertyName property to our OneToManyRelationshipMetadata request, as shown below \u2013<\/p>\n
\/\/create variable for onetomanyrelationship metadata.\r\nvar lookupFieldcreated = new OneToManyRelationshipMetadata\r\n\r\n{\r\n\r\n\/\/entity on which this field should be created\r\n\r\nReferencingEntity = referencingEntityName,\r\n\r\n\/\/entity with which relationship should be created\r\n\r\nReferencedEntity = logicalNameofEntity,\r\n\r\nSchemaName = relationshipSchemaName,\r\n\r\nReferencingEntityNavigationPropertyName = fieldSchemaName + \"_\" + logicalNameofEntity,\r\n\r\n};<\/pre>\nSo, after adding these two properties, the whole code to create the polymorphic attribute with a custom Referencing Entity Navigation Property Name becomes as below \u2013<\/p>\n
OrganizationRequest createMultilookupField = new OrganizationRequest\r\n{\r\n\r\nRequestName = \"CreatePolymorphicLookupAttribute\"\r\n\r\n};\r\n\u00a0\r\n\r\n\/\/ Create a new instance of BooleanManagedProperty\r\n\r\nBooleanManagedProperty boolManagedProperty = new Microsoft.Xrm.Sdk.BooleanManagedProperty();\r\n\r\n\r\nboolManagedProperty.Value = true;\r\n\r\n\r\ncreateMultilookupField.Parameters[\"Lookup\"] = new LookupAttributeMetadata()\r\n\r\n{\r\n\r\nSchemaName = fieldSchemaName,\r\n\r\nDisplayName = new Label(fieldDisplayName, languageCode),\r\n\r\nIsCustomizable = boolManagedProperty,\r\n\r\nDescription = new Label(description, languageCode)\r\n\r\n};\r\n\r\n\/\/create variable for onetomanyrelationship metadata.\r\n\r\nvar lookupFieldcreated = new OneToManyRelationshipMetadata\r\n\r\n{\r\n\r\n\/\/entity on which this field should be created\r\n\r\nReferencingEntity = referencingEntityName,\r\n\r\n\/\/entity with which relationship should be created\r\n\r\nReferencedEntity = logicalNameofEntity,\r\n\r\nSchemaName = relationshipSchemaName,\r\n\r\nReferencingEntityNavigationPropertyName = fieldSchemaName + \"_\" + logicalNameofEntity,\r\n\r\n\r\n};\r\n\r\n\r\ncreateMultilookupField.Parameters[\"OneToManyRelationships\"] = new OneToManyRelationshipMetadata[] { lookupFieldcreated };\r\n\r\nconfig.Service.Execute(createMultilookupField);<\/pre>\nConclusion<\/h2>\n
This is how we can create a custom referencing entity navigation property name by setting the IsCustomizable & LookupAttributeMetadata properties.<\/p>\n
