咱们关上一个 SAP 帮忙文档的页面，看到如下链接：

其中 q=site 表明查问关键字为 site，loio 前面是一串 guid：loio76a5e87baecd4900b2d0f16e3768354e
version=2205 表明 Commerce Cloud 的版本号。
在 SAP CRM 中 URL 对象以逻辑对象 (LOIO) 和物理对象 (PHIO) 的模式存储。
为了取得 LOIO 和 PHIO 的值，咱们须要应用办法:CL_CRM_DOCUMENTS=>GET_INFO_URL。
咱们须要将 INSTID_A + TYPEID_A + CATID_A 字段传递到数据库表 SKWG_BREL 作为输出。
函数 SDOK_LOIO_GET_URI 能够用来读取 url.
应用如下的代码，依据 loio guid，取得 document url：
TYPES : BEGIN OF l_typ_instid,
instid_a LIKE skwg_brel-instid_a,
END OF l_typ_instid.
** Get URL link

ENDLOOP.

ENDLOOP.SAP Document 存储反对如下几种形式：
- SAP DMS
- Generic Object Services
- Direct upload as in CRM, PPM
- Business Document Services
- Archivelink
以上办法除了 archivelink 外，都应用 LOIO 和 PHIO 类的概念在 SAP 中上传原始文件。除了 archivelink 外，每个文档上传办法都有链接的 PHIO 和 LOIO 类。SAP Object 链接到 LOIO id，原始文档链接到 PHIO id。每种文档上传办法的 LOIO id 和 PHIO id 之间存在肯定的关系。
默认状况下，对于除 archivelink 之外的每种文档上传办法，原始文档都存储在 SAP 数据库表中。对于 SDOKPHCL 表中针对各自的 PHIO 类的每个上传办法，都能够应用默认的 SAP 数据库表。如果须要，能够应用配置将这些原始文件定向到内容服务器。
