Historization

Overview

Historization is a dataflow diagram relationship that shows where AnalyticsCreator keeps a time-aware version of a table. Use it to review which operational or prepared table is historized, which history table stores the changing records, and which package maintains that history.

Function

A Historization flow connects a table with its history table and the package that executes the history load. In the diagram, this makes the change-tracking path visible beside the rest of the dataflow so you can see the current table, the history table, and the execution package together.

From a table node, the diagram menu can start a new historization. Existing historization relationships can be opened from the historization marker or from the navigation tree, where the relationship is listed as a history-table-to-table entry.

Use the Historization diagram view when checking where historical data is captured, whether the expected package owns the load, and whether the historized table is connected to the correct layer, schema, and source table.

Access

Open the dataflow diagram from the DWH area, then find the table or historization relationship you want to review. Historization entries are also available from the Packages branch and from schemas that contain historization definitions.
