使用 RetrieveMultipleRequest 检索相关实体

发布于 2024-10-16 23:02:06 字数 1083 浏览 3 评论 0原文

我有一个名为 Invoice 的实体和一个名为 InvoiceItem 的实体。

有一个名为 new_invoice_invoiceitem 的一对多关系。

InvoiceItem 中有一个名为 new_parent_invoice_invoiceitem 的 LookupAttribute。

我尝试使用以下代码检索与具有特定 ID 的发票相关的 InvoiceItems：

QueryExpression query = new QueryExpression();
query.EntityName = "new_invoiceitem";
query.ColumnSet = new AllColumns();
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "new_parent_invoice_invoiceitem";
condition.Values = new object [] { new Guid("fe1009cc-e034-49d5-bc59-ab4c3091a6f9") };
condition.Operator = ConditionOperator.Equal;

FilterExpression filter = new FilterExpression();
filter.AddCondition(condition);
query.Criteria = filter;

RetrieveMultipleRequest request = new RetrieveMultipleRequest();
request.Query = query;

RetrieveMultipleResponse response = (RetrieveMultipleResponse)crmService.Execute(request);
BusinessEntityCollection bec = response.BusinessEntityCollection;

代码运行没有错误，但 BusinessEntityCollection 始终为空，即使 Dynamics 中有记录。

知道我做错了什么吗？

谢谢，

原文

I have an entity called Invoice and an entity called InvoiceItem.

There is a one to many relationship called new_invoice_invoiceitem.

There is a LookupAttribute in InvoiceItem called new_parent_invoice_invoiceitem.

I am trying to retrieve the InvoiceItems that are related to the Invoice with a particular ID using the following code:

QueryExpression query = new QueryExpression();
query.EntityName = "new_invoiceitem";
query.ColumnSet = new AllColumns();
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "new_parent_invoice_invoiceitem";
condition.Values = new object [] { new Guid("fe1009cc-e034-49d5-bc59-ab4c3091a6f9") };
condition.Operator = ConditionOperator.Equal;

FilterExpression filter = new FilterExpression();
filter.AddCondition(condition);
query.Criteria = filter;

RetrieveMultipleRequest request = new RetrieveMultipleRequest();
request.Query = query;

RetrieveMultipleResponse response = (RetrieveMultipleResponse)crmService.Execute(request);
BusinessEntityCollection bec = response.BusinessEntityCollection;

The code runs without errors but the BusinessEntityCollection is always empty even though there are records in Dynamics.

Any idea what I'm doing wrong?

Thanks,

David
