Manual transformation

Overview

Manual transformation is the transformation type used when the transformation view is written and maintained manually. Use it when the required logic cannot be described well through the standard table, column, and reference grids, or when a specialist needs full control over the view definition.

Function

A Manual transformation stores a transformation name, schema, historization setting, optional persistence settings, and an editable view definition. AnalyticsCreator keeps the transformation in the repository and can create or refresh it in the data warehouse, while the transformation logic itself is maintained in the VIEW tab.

When this type is selected, the editor focuses on the VIEW tab and makes the view text editable. The standard table and reference grids are not the main editing surface for this type, because the transformation logic is supplied directly by the user.

Use the rename grid when a manual definition changes output column names. Adding the old and new names helps AnalyticsCreator preserve downstream metadata and references after the manual view is changed.

Access

Create a Manual transformation from the Transformation Wizard by selecting Manual, or open an existing one from the transformation list. Manual transformations can also be opened from the architecture diagram when the transformation is shown there.
