Historizised table

Overview

Historizised table identifies a table that stores historical versions of another table in AnalyticsCreator. Use this table type when changes in a business object must be preserved instead of overwritten.

Function

A Historizised table is created for a selected source table and keeps the generated history structure linked back to that original table. It is typically created through the Historization Wizard, where the target schema, target table name, package, SCD type, empty-record behavior, and Vault ID option are selected.

In the table editor, Historizised table remains an editable table definition. The table name, schema, business metadata, columns, calculated columns, scripts, and table definition can be reviewed and maintained, while the historization relationship is shown through the Hist of table field.

The editor also enables the Hub of table, Satellite of table, and Link of table selectors for history tables. These fields connect the history table to Data Vault structures when the historized output participates in vault modeling.

Access

Create a Historizised table from the Historization flow. Open an existing history table from the Tables list, the navigation tree, or the architecture diagram.
