Question

我正在BIDS中建立一份SSRS报告。我需要让最终用户能够根据批准状态过滤报告。但是，每行有四个单独的批准列 - 我们称之为ApprovalA，ApprovalB，ApprovalC和ApprovalD;每个状态确定该行的整体状态。四个中的每一个都可以具有四个值中的一个 - 已批准，正在进行，已拒绝或不适用。我的方法是根据所有四列是否为Approved和N / A或Rejected和N / A的某种组合，或者In Progress是否在任何列中，创建派生列;然后我会根据派生列进行过滤。但是，每次运行报告时，都会收到错误消息：

“[rsRuntimeErrorInExpression]字段'Approval_Status'的值表达式包含错误：输入字符串的格式不正确。”

据我所知，我的查询应该有效，但它很复杂，我还是SSRS的新手。任何建议都会很精彩。我对派生列的表达式如下：

=Switch((Fields!ApprovalA.Value OR Fields!ApprovalB.Value OR Fields!ApprovalC.Value OR Fields!ApprovalD.Value) = "Accepted" OR (Fields!ApprovalA.Value OR Fields!ApprovalB.Value OR Fields!ApprovalC.Value OR Fields!ApprovalD.Value) = "N/A", "Accepted", (Fields!ApprovalA.Value OR Fields!ApprovalB.Value OR Fields!ApprovalC.Value OR Fields!IsPFApproved.Value) = "Rejected" OR (Fields!ApprovalA.Value OR Fields!ApprovalB.Value OR Fields!ApprovalC.Value OR Fields!ApprovalD.Value) = "N/A", "Rejected", (Fields!ApprovalA.Value OR Fields!ApprovalB.Value OR Fields!ApprovalC.Value OR Fields!ApprovalD.Value) = "In Progress", "In Progress")

这样的事情可能起作用并复制你想要的逻辑：

=Switch(
  (Fields!ApprovalA.Value = "Accepted" OR Fields!ApprovalA.Value = "N/A")
    AND (Fields!ApprovalB.Value = "Accepted" OR Fields!ApprovalB.Value = "N/A")
    AND (Fields!ApprovalC.Value = "Accepted" OR Fields!ApprovalC.Value = "N/A")
    AND (Fields!ApprovalD.Value = "Accepted" OR Fields!ApprovalD.Value = "N/A")
    , "Accepted",
  (Fields!ApprovalA.Value = "Rejected" OR Fields!ApprovalA.Value = "N/A")
    AND (Fields!ApprovalB.Value = "Rejected" OR Fields!ApprovalB.Value = "N/A")
    AND (Fields!ApprovalC.Value = "Rejected" OR Fields!ApprovalC.Value = "N/A")
    AND (Fields!ApprovalD.Value = "Rejected" OR Fields!ApprovalD.Value = "N/A")
    , "Rejected",
  Fields!ApprovalA.Value = "In Progress"
    OR Fields!ApprovalB.Value = "In Progress"
    OR Fields!ApprovalC.Value = "In Progress"
    OR Fields!ApprovalD.Value = "In Progress"
    , "In Progress"
)

你有语法错误;类似的东西：

(Fields!ApprovalA.Value
  OR Fields!ApprovalB.Value
  OR Fields!ApprovalC.Value
  OR Fields!ApprovalD.Value) = "Accepted"

会导致错误，因为每个子句需要求值为布尔值;你不能那样嵌套这些字段。
