新建 的BOS单据，并启用了审批流。用K3API调用相关单据却提示，当前单据已经启动多级审核。可单据并没有启动多级审核，不知道是为什么。K3客户端上是可以启动多级审核的，可API调用就是有问题。JSON串：
{

"Data": {
"FBillNo": "GCHL000009",
"FChecker": "kingdee",
"FCheckDirection": "1",
"FDealComment": ""
}
}
返回的提示：
{
"StatusCode": 1801,
"Message": "当前单据已经启动多级审核！",
"Data": null
}

FCheckDirection设置为2

这么简单的问题，金蝶的大神们都没人来回答。看样子用的人是少。
