从 Power BI 中的 Azure DevOps 创建跨组织的 Sprint Burndown 图表

Question

我有以下查询来在 Azure DevOps 中构建 Sprint Burndown 跨组织。它工作正常且流畅。

OData.Feed ("https://analytics.dev.azure.com/" & organization & "/" & projectName & "/_odata/v3.0-preview/WorkItemSnapshot?"
        &"$apply=filter(WorkItemType eq 'User Story'  and StateCategory ne 'Completed' and DateValue ge Iteration/StartDate and DateValue le Iteration/EndDate and Iteration/StartDate ge 2020-01-01Z)"
        &"/groupby( "
            &"(DateValue,State,WorkItemType,Area/AreaPath,Iteration/IterationPath,Iteration/StartDate,Iteration/EndDate), "
            &"aggregate($count as Count, StoryPoints with sum as TotalStoryPoints) "
        &") ",
    [#"Authorization" = "Basic " & apiKey]
    , [Implementation="2.0",OmitValues = ODataOmitValues.Nulls,ODataVersion = 4])

但是，我也想查询每个项目下的团队，但与迭代和区域相比，它不像在 groupby 部分中添加 Teams/TeamName 那样简单。

以下是我失败的尝试：

OData.Feed ("https://analytics.dev.azure.com/" & organization & "/" & projectName & "/_odata/v3.0-preview/WorkItemSnapshot?"
        &"$apply=filter(WorkItemType eq 'User Story'  and StateCategory ne 'Completed' and DateValue ge Iteration/StartDate and DateValue le Iteration/EndDate and Iteration/StartDate ge 2020-01-01Z)"
        &"/groupby( "
            &"(DateValue,State,WorkItemType,Teams/TeamName,Area/AreaPath,Iteration/IterationPath,Iteration/StartDate,Iteration/EndDate), "
            &"aggregate($count as Count, StoryPoints with sum as TotalStoryPoints) "
        &") ",
    [#"Authorization" = "Basic " & apiKey]
    , [Implementation="2.0",OmitValues = ODataOmitValues.Nulls,ODataVersion = 4])

Answer 1

我发现更有效的方法是使用另一个 OData 端点 WorkItemBoardSnapshot，我可以在其中执行服务器端 groupby，这比在 Power BI 中执行要高效得多。

这里有一些参考：

OData.Feed ("https://analytics.dev.azure.com/" & organization & "/" & projectName &"/_odata/v3.0-preview/WorkItemBoardSnapshot?"
        &"$apply=filter(WorkItemType eq 'User Story'  and StateCategory ne 'Completed' and DateValue ge Iteration/StartDate and DateValue le Iteration/EndDate and Iteration/StartDate ge 2020-01-01Z)"
        &"/groupby("
            &"(DateValue,WorkItemType,Team/TeamName,Iteration/IterationPath,Iteration/StartDate,Iteration/EndDate),"
            &"aggregate($count as Count, StoryPoints with sum as TotalStoryPoints)"
        &")",
    [#"Authorization" = "Basic " & apiKey]
    , [Implementation="2.0",OmitValues = ODataOmitValues.Nulls,ODataVersion = 4])

差异将WorkItemSnapshot 更改为WorkItemBoardSnapshot 并注意板快照使用Team 而不是Teams。
