WebAPI“简单生产入库单”示例中的JSON格式不能用

求“简单生产入库单” 正确的JSON格式。WebAPI中的示例格式不能用!

以下是我根据各种文档写出来的，但结果不对。

{
\"Creator\": \"Creator_String\",
\"NeedUpDateFields\": [
\"\"
],
\"Model\": {
\"FID\": 0,
\"FDate\": \"2015-08-10\",
\"SP_InStock__FEntity\": [
{
\"FMaterialId\": {
\"FNUMBER\": \"301\"
},
\"FBaseRealQty\": 10,
\"FRealQty\": 10,
\"FUnitID\": {
\"FNUMBER\": \"tang\"
},
\"FWorkShopId1\": {
\"FNUMBER\": \"BM000003\"
},
\"FStockId\": {
\"FNUMBER\": \"CK001\"
}
}
],
\"FBillType\": {
\"FNUMBER\": \"JDSCRK01_SYS\"
},
\"FStockOrgId\": {
\"FNUMBER\": \"10202\"
},
\"FPrdOrgId\": {
\"FNUMBER\": \"10202\"
},
\"FOwnerId0\": {
\"FNumber\": \"10202\"
},
\"FCreatorId\": {
\"FUserAccount\": \"demo\"
},
\"FCreateDate\": \"2015-08-10\"
}
}

结果：

"ErrorCode": 500,
"IsSuccess": false,

{
"FieldName": "FWorkShopId1",
"Message": "单据体“明细”第1行字段“生产车间”是必填项"
