Hana Studio Tips & Tricks: Lineage

Home / SAP HANA / Hana Studio Tips & Tricks: Lineage

Graphical calculation views can be very complex – when a view consist of many nodes (joins, unions, projections), it is difficult to find what is the source (table, another view) of the field is.

When you need to find the original value, which is common during troubleshooting, it is not convenient to click from node to node to find the source table or the source view.

In such cases Show Lineage button is helpful.

  2. Select the field (line on right side).

The path is marked like in the picture below.
