The Batch Orchestration is the implementation of a data pipeline within the data warehouse.

A master batch is the highest functional batch you can create.
To create a new master batch, right-click on the RootBatch to open the context menu of the root batch and choose "Create new Master Batch":
In the following dialog you have to write the name of the new batch in the input field (Child Batchlabel) . Then click "Create" to add the new master batch.
With the companion app you are able to configure a dependency relation between batches, to orchestrate the load process of the batches. A dependency is always a structure like [successor -> predecessor]. This means, that all process steps of the successor have to be loaded after the predecessor process steps are finished.
In the app, select the batch which should be a successor of another batch and right-click on that batch to open his context menu and click on "Options" and "Dependencies".
In my example I want to start the load of the Batch Sub A.3 after the Batch Sub A.2 - so Sub A.3 has the predecessor Sub A.2:
The app presents all candidates for the successor (which are all sibling batches). Select all batches which should be predecessors of the current batch and click "Save":
The result is a visible dotted line between the batches to represent a dependency. If you hover over a batch, the dependency will animate in the direction of the dependency:
