The Data Lineage diagram of a Model Object shows all the dependencies of a Model Object with other Model Objects using both top-down and bottom-up (upstream and downstream) approaches:
- Predecessor Model Objects: You can see all the upstream Model Objects (related to the Model Object with or without a Mapping). They represent the entities that influence or feed into the current Model Object.
- Successor Model Objects: You can see all the downstream Model Objects (linked to the Model Object with or without a Mapping). They signify the entities that are influenced by or dependent on the current Model Object.
