我们打开一个 SAP 帮助文档的页面，看到如下链接：

其中 q=site 表明查询关键字为 site，loio 后面是一串 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)的形式存储。
为了获得LOIO和PHIO的值，我们需要使用方法:CL_CRM_DOCUMENTS=>GET_INFO_URL。
我们需要将 INSTID_A + TYPEID_A + CATID_A 字段传递到数据库表 SKWG_BREL 作为输入。
函数 SDOK_LOIO_GET_URI 可以用来读取 url.
使用如下的代码，根据 loio guid，获得 document url：
TYPES : BEGIN OF l_typ_instid,
instid_a LIKE skwg_brel-instid_a,
END OF l_typ_instid.
** Get URL link
