Dataflow Model lifecycle

In their life-cycle, models can have 2 statuses: draft and master.

When created, models are in status draft, i.e. they are not associated with incoming dataflows.

Once promoted to masters, models can be used to enrich incoming dataflows.

Models in draft status can be edited.
Models in master status cannot be edited.

If you need to modify a master version, you must create an editable copy of the model by clicking the SAVE button on the Dataflow Modeler toolbar and then selecting Open Draft Version. Apply your changes and save the model again in draft or master.

Let's look at the Flow Model Lifecycle from creation (draft status) to delivery (master status):

By clicking the SAVE button on the Dataflow Modeler toolbar, the following menu appears allowing you to manage the Dataflow Model lifecycle:

• Save: the model is saved in draft status for further changes.
• Save as new Model: a new model is created in draft status. The new model created has the same settings as the original model.
• Promote as Master Version: the model is saved in master status and can no longer be modified.
• Open Draft Version: this menu is used to edit a model saved as master. By selecting this option, the master model is set to draft and becomes editable. When saving the edited draft version to master, the previous master version will be overwritten.
