Omniture数据仓库API不允许Date_Granularity的“小时”值

使用Omniture Data Warehouse API Explorer时( https://developer.omniture.com/en_US/get-started/api-explorer#DataWarehouse.Request ),以下请求提供了“Date_Granularity是无效响应”。有人有这方面的经验吗?API文档( https://developer.omniture.com/en_US/documentation/data-warehouse/pdf ),表示可以接受以下值:“none、hour、day、week、month、quarter、year。”

{
"Breakdown_List":[
    "evar14",
    "ip",
    "evar64",
    "evar65",
    "prop63",
    "evar6",
    "evar16"
],
"Contact_Name":"[hidden]",
"Contact_Phone":"[hidden]",
"Date_From":"12/01/11",
"Date_To":"12/14/11",
"Date_Type":"range",
"Email_Subject":"[hidden]",
"Email_To":"[hidden]",
"FTP_Dir":"/",
"FTP_Host":"[hidden]",
"FTP_Password":"[hidden]",
"FTP_Port":"21",
"FTP_UserName":"[hidden]",
"File_Name":"test-report",
"Metric_List":[ ],
"Report_Name":"test-report",
"rsid":"[hidden]",

"Date_Granularity":"hour",
}

回复:

{  
"errors":[
    "Date_Granularity is invalid."
]
}
