SSIS:执行执行包任务时出错

SSIS: Error when executing a Execute Package Task

我有一个项目,其中有 1 个主包和几个在主包中调用的子包。 然而,当我启动主包时,它在一个 "Execute Package Task" 上出错 请参阅下面的 Output-Window:

的输出
Information: 0x40016042 at build_NAV_sources: The package is attempting to configure from the parent variable "var_actual_timestamp".
.
.--more variables configuration
.
Information: 0x40016042 at build_NAV_sources: The package is attempting to configure from the parent variable "var_table_prefix".
Error: 0xC00220E0 at Execute Package Read Dim norriq data to sources: The connection is not specified.
Error: 0xC0024107 at Execute Package Read Dim norriq data to sources: There were errors during task validation.
Error: 0xC00220E4 at Execute Package build nav sources: Error 0xC0012050 while preparing to load the package. Package failed validation from the ExecutePackage task. The package cannot run.
.
Task failed: Execute Package build nav sources
SSIS package "F:\Workspaces\KPA\TFS\Norriq\BI\SQL 2012\NAV 2015\SSIS\NAV Datamart\build_NAV_datamart_master.dtsx" finished: Success.

当我检查指示未指定连接的包时,我清楚地看到指定了一个连接。在我的连接管理器中,我看到了连接,当我编辑这个连接并检查连接时,一切正常。

更奇怪的是:当我单独启动程序包 (build_NAV_sources) 时,它执行时没有任何错误或警告

有人知道发生了什么事吗?

感谢

在不更改任何重要内容的情况下,我在 TFS 中签入了我的解决方案,关闭了 VS,再次打开了解决方案并执行了 build/rebuild 并且它神奇地工作了。
