CRM Dynamics插件代码问题2015

Question

我正在尝试为Microsoft CRM Dynamics 2015（版本7.0.2）创建一个插件，但无法正常工作。 该插件将在创建案例后运行，并将尝试从帐户中恢复合同信息。

我有以下代码，它不起作用（合同信息未保存在案例/事件中）。

编辑

我更新了代码，但现在失败了，但是在系统作业上或使用插件注册工具进行调试时，并没有给出明确的错误。

系统作业错误消息：System.ServiceModel.QuotaExceededException：Microsoft Dynamics CRM遇到错误。 管理员或支持者的参考编号：＃1C10449A

使用Visual Studio和插件注册工具进行调试一直很顺利，直到尝试调用Update方法为止为止，在该方法中该事件不存在，但是由于它是同步插件，因此未创建该事件（这是获取日志的唯一方法）能够调试我发现的东西）。

public class CaseContractFill : IPlugin
{
    Contract checkForContract(Guid accountId, IOrganizationService service)
    {

        QueryExpression accountContractQuery = new QueryExpression
        {
            EntityName = Contract.EntityLogicalName,
            ColumnSet = new ColumnSet(true),
            Criteria = new FilterExpression
            {
                Conditions = 
                {
                    new ConditionExpression 
                    {
                        AttributeName = "accountid",
                        Operator = ConditionOperator.Equal,
                        Values = { accountId }
                    }
                }
            }
        };

        DataCollection<Entity> accountContracts = service.RetrieveMultiple(accountContractQuery).Entities;

        //Check if account has a contract and return it
        if (accountContracts.Count > 0)
        {
            return (Contract)accountContracts[0];
        }

        //Retrieves account
        Account account = (Account)service.Retrieve(Account.EntityLogicalName, accountId, new ColumnSet(true));

        //Check if account has a parent and call this method again with that parent
        if (account.ParentAccountId != null)
        {
            checkForContract(account.ParentAccountId.Id, service);
        }

        //If no Contract and/or no Parent returns null
        return null;

    }

    ContractDetail checkForContractLine(Guid contractId, IOrganizationService service)
    {
        QueryExpression accountContractQuery = new QueryExpression
        {
            EntityName = ContractDetail.EntityLogicalName,
            ColumnSet = new ColumnSet(true),
            Criteria = new FilterExpression
            {
                Conditions =

                    new ConditionExpression

                        Operator = ConditionOperator.Equal,
                        Values = { contractId }
                    }
                }
            }
        };

        DataCollection<Entity> contractLines = service.RetrieveMultiple(accountContractQuery).Entities;

        return (ContractDetail)contractLines[0];
    }

    public void Execute(IServiceProvider serviceProvider)
    {
        ITracingService tracer = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
        IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
        IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        IOrganizationService service = factory.CreateOrganizationService(context.UserId);

        try
        {
            Entity entity = (Entity)context.InputParameters["Target"];                
            Incident incident = (Incident)entity.ToEntity<Incident>();

            Contract contract = checkForContract(incident.CustomerId.Id, service);

            if (contract != null)
            {
                incident.ContractId = contract.ToEntityReference();

                ContractDetail contractLine = checkForContractLine(contract.Id, service);
                incident.ContractDetailId = contractLine.ToEntityReference();

                service.Update(incident);
            }
        }
        catch (Exception e)
        {
            throw new InvalidPluginExecutionException(e.Message);
        }
    }
}

Answer 1

错误分配了“ ContractId”。

if (contract != null)
{
  incident.ContractId = contract.ToEntityReference();
  service.Update(incident);
}

Answer 2

当您通过IOrganizationService.Retrieve获取实体时， account.contract_customer_accounts将为空，就像所有其他关系一样。

您可以单独调用该服务以使用RetrieveMultiple获取相关合同，也可以考虑使用OrganizationServiceContext 。
