Question

当我试图显示水晶报告或导出时，我收到错误。我无法理解阅读错误消息。我已将水晶报告与数据集绑定，并正确发送水晶报告参数。请帮我解决问题。

Answer 1

我看到Error Logon failed...incorrect log on parameters。您是否尝试过数据库 - ＆gt;验证数据库？

或者，看看这个。这听起来很熟悉吗？ Crystal Report: Unable to connect incorrect log on parameters

Answer 2

如果此报告中包含子报告，则还必须显式设置子报告的数据源。仅将整个数据集设置为主报表数据源是不够的。
