{[Result, {
"ResponseStatus": {
"ErrorCode": 500,
"IsSuccess": false,
"Errors": [
{
"FieldName": "MapComplexProperty Field Error ：Field Key is 【FCustomerID】",
"Message": " 在 Kingdee.BOS.WebApi.FormService.MapPropertyService.MapComplexProperty(String pkProperty, Dictionary`2 sourceObj, DynamicObject targetObj, Int32 rowIndex, HashSet`1 NeedUpDateFields)\r\n 在 Kingdee.BOS.WebApi.FormService.Save.Execute()\r\n 在 Kingdee.BOS.WebApi.FormService.BillOperationService.ExecuteOperation(FormOperation op, String data)",
