Crystal Reports图表详细信息抑制

[英]Crystal Reports Chart Detail Suppression

原文 2013-04-11 05:09:39 5 1 c#/ crystal-reports

I have multiple entries each which can have one or more approval stages (with a date). 我有多个条目，每个条目可以有一个或多个批准阶段（带有日期）。 I've been able to use grouping/detail suppression to only retrieve the latest approval stage (as we don't care if it was submitted if it's currently final approval) but no matter what I try the chart always shows every single record which brings back information we don't need to see. 我已经能够使用分组/详细信息抑制功能来仅检索最新的批准阶段（因为我们不在乎它是否是当前的最终批准而已提交），但是无论我尝试什么，图表始终会显示每条记录，返回我们不需要看到的信息。

Does anyone know how to fix this chart so that it only brings back the latest approval stage for each entry (with multiple approval stages)? 有谁知道如何修复此图表，以便仅为每个条目（具有多个批准阶段）返回最新的批准阶段？

Charts, like cross-tabs, act on all of the data in the report. 图表像交叉表一样，作用于报表中的所有数据。 You will need to build the report in a way that the extraneous data is removed. 您将需要以删除无关数据的方式来构建报告。

I would recommend using a SQL-expression field to identify the latest approval stage, then reference this field in the record-selection formula. 我建议使用SQL表达式字段来标识最新的批准阶段，然后在记录选择公式中引用此字段。 See my posting: Crystal Reports: Using SQL Expression Fields . 请参阅我的文章：《 Crystal Reports：使用SQL表达式字段》。
