Can You Update Entity Attribute In PostOperation?

Posted on by Community Member

I have a plugin that is registered like this:

[CrmPluginRegistration(MessageNameEnum.Create,
    "contractdetail",
    StageEnum.PostOperation,
    ExecutionModeEnum.Asynchronous,
    "",
    "Post-Invoice Contract",
    1,
    IsolationModeEnum.Sandbox)]

I am trying to update an attribute within the target entity like this:

                    //Update Contract Line StartDate
                    Entity updatedContractLine = new Entity(entity.LogicalName)
                    {
                        Id = entity.Id
                    };
                    updatedContractLine["activeon"] = startDate;
                    service.Update(updatedContractLine);

I know that a PostOperation means that the created entity has already been committed to the database and I am fine with that. I want the "activeon" attribute to be updated after it is created. For some odd reason, the attribute is not updating! Can someone explain why?!

I think we will need to see the rest of your plugin especially that are retrieving the entity details from the context. You are looking at the output parameters as this is running asynchronously after the record was created?

Hmm. This should work. Did you debug or can you add trace and see?

Do you have any depth check or any asynchronous update plugin - check for any other exception which may rollback.

Here is the rest of the plugin:

public class UnitPluginPostInvoice : IPlugin { public void Execute(IServiceProvider serviceProvider) { // Extract the tracing service for use in debugging sandboxed plug-ins. // Will be registering this plugin, thus will need to add tracing service related code. ITracingService tracing = (ITracingService)serviceProvider.GetService(typeof(ITracingService)); //obtain execution context from service provider. IPluginExecutionContext context = (IPluginExecutionContext) serviceProvider.GetService(typeof(IPluginExecutionContext)); // InputParameters collection contains all the data passed in the message request. if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity) { Entity entity = (Entity)context.InputParameters["Target"]; if (entity.LogicalName != "contractdetail") return; //obtain the organization service for web service calls. IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId); //Core Plugin code in Try Block try { //get contractid lookup field value var contractLookup = entity.GetAttributeValue<EntityReference>("contractid"); //Retrieve associated contract var contract = service.Retrieve(contractLookup.LogicalName, contractLookup.Id, new ColumnSet(true)); //if associated contract is not invoiced, return if (contract.GetAttributeValue<OptionSetValue>("statecode").Value != 1) return; //Get Contract line start date var startDate = DateTime.Today; //Update Contract Line StartDate Entity updatedContractLine = new Entity(entity.LogicalName) { Id = entity.Id }; updatedContractLine["activeon"] = startDate; service.Update(updatedContractLine); //Get Contract Line End Date DateTime endDate = (DateTime)entity["expireson"]; //Get Contract range into weekdays list Eachday range = new Eachday(); var weekdays = range.WeekDay(startDate, endDate); //Get Unit Order Lookup Id EntityReference unitOrderLookup = (EntityReference)contract.Attributes["new_unitorderid"]; var unitOrderLookUpId = unitOrderLookup.Id; //Get the contract Id to string for FetchXML var contractId = contract.Id.ToString(); //Retrieve Unit Order var unitOrder = service.Retrieve(unitOrderLookup.LogicalName, unitOrderLookUpId, new ColumnSet(true)); var unitOrderId = unitOrder.Id; var uiName = unitOrder.GetAttributeValue<string>("new_name");

As you are post operation you should be using context.OutputParameters.Contains("Target") instead of the context.InputParameters.Contains("Target") you are using above.

Post operation the target entity is not part of the InputParameters and is part of the OutputParameters so your plugin is currently triggering, checking for a target entity and then skipping the rest of the code as the target entity doesn't exist.

Also (as an aside) on create the target entity in the input context does not contain the Id of the record as the id of the record only exists after its been created (hence it only appears in the output parameters).

To expand on the previous post, on a Create message, the Target InputParameter won't have the .Id set (unless it is explicitly passed in the Create). Instead, use the Id OutputParameter to get the Id of the new record
