求教JCo连接SAP调用RFC函数能获取到表结构却取不到数据!

[qq_32145293]

SapUtil工具类(获取JCoParameterList对象):
public static JCoParameterList getJCoTable(String funcName){
//读取配置文件,获取JCoDestination对象
JCoDestination dest = null;
try {
dest = JCoDestinationManager.getDestination("ECC");
dest.ping();
} catch (JCoException e) {
e.printStackTrace();
//连接到SAP失败
throw new ServiceRuntimeException("连接到SAP失败,请稍后重试!");
}

JCoFunction func = null;
try {
func = dest.getRepository().getFunction(funcName);
} catch (JCoException e) {
e.printStackTrace();
//创建function对象失败
throw new ServiceRuntimeException("连接到SAP失败,请稍后重试!");
}

if(func == null){
//获取到的function对象为null
throw new ServiceRuntimeException("连接到SAP失败,请稍后重试!");
}

//获取table 接口对象 供后续获取数据使用
JCoParameterList tmlist = func.getTableParameterList();

return tmlist;
}

junit测试代码:
public void test(){
JCoParameterList tmlist = SapUtil.getJCoTable("ZFIF_GET_YY001");
JCoTable cgfpTab = tmlist.getTable("CGFP_OUT");
System.out.println(cgfpTab);
//应该返回一条数据
Assert.assertEquals(1,cgfpTab.getNumRows());
}

断言返回错误:

获取到的表结构部分:

| TABLE 'ZFIS0005'
|--------|--------|----------|---|--------|----------------|----------|------------------|---|----------------|----------------|----|----------------|----------------|----------------|----------------|----------|-----|----------|----|
|BLDAT |BUDAT |BELNR |BUZ|FPLX |XBLNR |LIFNR

jco.client.sysnr=10
jco.client.user=*********
jco.destination.peak_limit=40
jco.destination.pool_capacity=5
jco.client.saprouter=/H/***.***.***.***/H/

是否有数据？ 你用的用户是否有访问权限？

[qq_32145293]

感谢，已经解决了这个问题，数据存在且用户具有访问权限，需要调用function.excute(destination);方法然后对应的JCoTable内就会有数据。但是具体的原因还不是很清楚。
