About Siebel Universal Customer Master Data Hierarchy
Siebel UCM supports the use of account data hierarchies with the master customer data, and includes screens to display and view the account hierarchies. Siebel UCM also supports copying existing hierarchies with their existing relationships.
Three new tables allow for this functionality: S_DYN_HRCHY, which stores hierarchy information as a header; S_DYN_HRCHY_REL, which stores relationships; and S_DYNHR_RPT_REL, which stores denormalized hierarchy relationships.
For further background information on data hierarchy concepts, see Siebel Applications Administration Guide.
