Generating Virtual Preview of Targets

When you create a mapping specification, source column values undergo modifications based on the applied transformations. These modified values are updated in target columns based on the target update strategy. You can generate a virtual preview of targets to view the updated target columns.

Note: Mapping specifications involving multiple source or target systems do not support virtual preview of targets.

To generate a virtual preview of targets, follow these steps:

  1. Go to Application Menu > Data Catalog > Mapping Manager.
  2. In the Workspace Mappings pane, click a map.
  3. The Mapping Specification grid appears.

  4. Click .
  5. Mapping Preview page appears, displaying the virtual preview of the target based on the source and transformations.

    Note: Mapping preview is currently supported for RDBMS only. Here is the list of transformation supported in Mapping Preview:

    CONCAT, LTRIM, RTRIM, TRIM, CEIL, FLOOR, RPAD, LPAD, ROUND, SQRT, SUBSTR, UPPER, LOWER, TRUNC, SIN, COS, TAN, SINH, TANH, REVERSE, IS_DATE, IS_NUMBER, IS_SPACES, ISNULL, IIF, ISEMPTY, NVL, DECODE.

    You can download the mapping preview details in the XLSX format. To download the mapping preview details, click .
