这篇SAP社区博客里，我的一位同事介绍了SAP Marketing里contact facet数据模型的存储表：

主要是这两张表：

CUAND_CE_IC_ROOT

CUAND_CE_IC_FCET

现在我的需求是：对系统里Contact的Origin Data数据来源渠道个数从高到低的顺序进行排序：

解决方案：开发两个CDS view

  1. zcontact_origin
@AbapCatalog.sqlViewName: 'SQL_VIEW_NAME'@AbapCatalog.compiler.compareFilter: true@AbapCatalog.preserveKey: true@AccessControl.authorizationCheck: #CHECK@EndUserText.label: 'Contact Origin tool'define view zcontact_origin as select from cuand_ce_ic_root as a inner join  cuand_ce_ic_fcet as b on a.db_key = b.parent_key  {   key a.db_key,   a.name_text,   a.smtp_addr,   b.db_key as children_key,   b.id_origin}
  1. zcontact_count
@AbapCatalog.sqlViewName: 'ZCONCOUNT'@AbapCatalog.compiler.compareFilter: true@AbapCatalog.preserveKey: true@AccessControl.authorizationCheck: #CHECK@EndUserText.label: 'count aggregation'define view ZCONTACT_COUNT as select from zcontact_origin {   key zcontact_origin.db_key,   zcontact_origin.smtp_addr,   count(*) as facet_count} group by db_key, smtp_addr
