在Crystal报表中计算参数 [英] Calculation for a parameter in crystal reports

问题描述

hi ..

我解决了这个问题，需要解决方案.

我有一份生成报告的水晶报告..
在帐单中，它包含该项目的金额以及适用于该金额的费用.

如果费用的描述为"ADD"，则必须将其添加到项目总计中，如果其描述为"LESS"，则应从项目总计中扣除，最终金额应显示为总计.

该报告显示了所有数据，我试图获取一个名为total的变量，并在它的字段资源管理器中编写了此代码..

hi..

I cam across this problem and need a solution.

I have a crystal report which generates a bill..
In the bill it includes the amount for the item and the charges that applies to the amount.

If the charges have description "ADD" , it must be added to the item total and if it has description "LESS" it should be deducted from item total and final amount should be displayed as total.

The report displays all the data, I tried to take a variable named total and on its field explorer i wrote this..

int _total;
if({Expensedetail.add_less}=''add'')
{
_total=_total+{Expensedetail.Amount};
}
else
{
_total=_total-{Expensedetail.Amount};
}

this is not working...can you guys please suggest me what to do??

推荐答案

您是否已在公式编辑器中编写了此代码?是否保存没有任何错误?

我认为您需要阅读"WhilePrintingRecords"的功能...

Have you written this code in the formula editor? Does it save without any errors?

I think you will need to read up on what "WhilePrintingRecords" does...
