Manage Lineage

The Manage Lineage feature enables you to view and control the structure of the lineage. It allows you to add, modify, or delete nodes and their relationships to build an accurate representation of the required dependency structure.

Lineage updates can be performed using either the Complete Lineage Report or the Lineage Template, depending on your preferred method of input.

Using Complete Lineage Report

Follow the below steps to modify the lineage:

Click the Manage Graph icon.

Click Download Complete Lineage to update, add, or delete the nodes and their relationships in the current lineage.

Once the complete lineage report is downloaded, you can make necessary updates such as updating, deleting or adding the nodes and its relationships.
After making the required changes, upload the updated lineage report in Upload to Modify Lineage.
Click Apply to incorporate the updates into the dependency structure.
Generate the required process or data lineage.

Using Lineage Template

Follow the below steps to add new nodes and their relationships to the current lineage report:

Click the Manage Graph icon.

Click Download Lineage Template.

Once the lineage template is downloaded, you can add new nodes and relationships in the template.
After making the required changes, upload the template in Upload to Modify Lineage.
Click Apply to incorporate the updates into the complete dependency structure.
Generate the required process or data lineage.

Important:

To effectively manage lineage, you must adhere to the following rules:

Do not modify the column headers or their order in the Complete Lineage report or the Lineage template. The following are the column headers: source_name, source_type, target_name, target_type, relation_type, and database_id.
When deleting a row, retain the value in the database_id column and clear all the other column values.
When inserting a row, add all the column values except in the database_id column.
When updating a row, ensure that all the columns have relevant data.
