希望为水晶报告提供帮助

问题描述:

我有一份报告

收入:费用

日期类型金额日期类型金额差异
-AAAA 4000 ---- 500?



这是页脚

总收入总和


我要收支差额

我该怎么做?

I have one report

Income: Expense

date type Amount Date type Amount diffrence
--- AAAA 4000 ---- 500 ?



This is the footer

sumof Income SumofExpense


I want difference of Income and Expense

How can I do this?

1.将公式字段(说@Balance)添加为{YourTable.Income} - {YourTable.Expense}
2.显示公式字段(@Balance)
3. @Balance字段上的总计
你完成了

但我建议您阅读更多有关水晶报告的内容.
1. Add a Formula Field (Say @Balance) as {YourTable.Income} - {YourTable.Expense}
2. Show the Formula field(@Balance)
3. Total on @Balance field
and you are done

But I would suggest read some more on crystal report.
