覆盖订阅中的现有文件名

Question

我有一个部署 .rss 文件的批处理文件。 rss 文件包含为 10 个报告创建订阅的脚本。一旦部署批处理文件，.rss 文件就会被触发，从而在“报告管理器”中创建订阅（对于所有 10 个报告）。 我的问题是，每次部署批处理文件时都会创建一组新的订阅。即）创建一组新的重复项，而不是覆盖现有订阅。我最终获得了一份报告的许多订阅。 我需要一个在部署时覆盖现有文件的脚本。我必须使用任何方法吗？ 需要帮助..

创建订阅的代码：这非常混乱！请耐心等待..:)

Dim i as Integer = 0

Dim items As CatalogItem() = rs.ListChildren(fullpath, False)

        If item.Type = ItemTypeEnum.Report Then
    i = i + 1
    desc = item.name                
    report = fullpath &"/" & desc

可能这只是一个管道错误，使用>>而不是 >。代码示例会很好。
