脚本只能运行一遍，运行两边遍时就出错，请问是什么原因呢？

ruoyu82

录制的脚本如下：
Action()
{
        web_service_call( "StepName=SearchRestaurants_103",
                "SOAPMethod=ContentService.IContentService.SearchRestaurants",
                "ResponseParam=response",
                "WSDL=http://10.10.50.65/LBCMSLite?WSDL",
                "UseWSDLCopy=1",
                "Snapshot=t1243933951.inf",
                BEGIN_ARGUMENTS,
                "Culture=en-GB",
                "MaximumResults=100",
                "StartIndex=0",
                "xml:Search=<Search><For><CompanyNumber>C-001</CompanyNumber></For>"
                                "<ReturnDeleted>1</ReturnDeleted><ReturnDisabled>1</ReturnDisabled></Search>",
                END_ARGUMENTS,
                BEGIN_RESULT,
                "Restaurant/Id=Param_Id",
                END_RESULT,
                LAST);
        lr_think_time(3);
        return 0;
}
奇怪的是如果用两个用户迭代一次或者一个用户迭代两次执行，都会报错：提示不能输入多个companynumber（程序里设计的只能传递一个）。当用一个用户迭代一次就没有问题，是不是有缓存需要清除？还是别的什么原因，希望大家给予一些帮助，谢谢啦~

从这基本可以确定是参数问题，确认一下你的参数值的规则和参数来源吧，即你的这个参数同一个值能否重复使用，及你的参数值是服务器给你的还是你自己定义的。

感谢您的回复，choice类型是要求一次只能传递一个参数的。参数的值是我设置的。
我觉得好像第二次迭代时，应该是loadrunner传了两个companyNumber，所以才会给出这样的提示。
我重新定义了参数：改为unique+each iteration类型，定义了两个值C-001和c-002。运行后log如下：
g iteration 1.

从log里看第二次迭代开始的时候定位参数的取值，然后给参数取了c-002，但是如果仅是一个参数的话，不应该会报error的呀，应该是把第一次迭代的companyNumber也试图传递给服务器造成的吧，但是为什么要传第一次迭代的companyNumber呢？不太明白，希望大家不吝赐教...
