About Implicit Joins

Implicit joins exist as part of the Siebel object architecture. They are not explicitly defined using Siebel Tools. Unlike joins that you define in Siebel Tools, users can update the columns from implicit joins.

Implicit joins exist for the following:

• All 1:1 (_X) extension tables and all relevant intersection tables.
• Extension tables of S_PARTY, such as S_ORG_EXT, S_CONTACT, S_POSTN, and S_USER. These implicit joins are used to map data to party business components. For example, if you were to add a field to the Account business component and then selected the Join property, you would see several implicit joins that do not appear in the Join list displayed in the Tools Object List Editor, including joins with an alias of S_ORG_EXT and S_USERs.

Implicit joins usually use the table name as the Join Alias.
