Our integration is almost finished: At the top right of the integration canvas you will see the overall completion progress which now states 87%. Our final task is to configure the field(s) we want to track our instances on:

At the top right click Tracking to open the business identifiers dialog. Business identifiers enable runtime tracking on messages. Instance tracking is important to trace messages across integration flows. Any values selected are written into log files, so be careful not to use sensitive values as the logs are readable by anyone with access rights. We can specify up to three tracking fields, but a primary identifier is required. Drag and drop both maxResults and startWith to the list. Click Done to save the identifiers as shown in the following screenshot:

Notice at the top right corner that the completion progress states 100%, which means our integration is done. Click Save and Exit Integration to finish our first integration. We are returned back to the list of all integrations which will include our newly created integration at the top. Integrations need to be activated first before they are available for use as shown in the following screenshot:

Click the PENDING ACTIVATION button, this will show a Confirmation dialog. In this dialog, we get the choice to enable tracing. This should be handled with care because, as as the dialog explains, this isn't recommended in a production environment, but can be used for debugging purposes. In our case keep it disabled and click Yes as shown in the following screenshot:

Activation checks the connectivity of the used connections and validates the integration. Activation can fail, but we will discuss this in a later chapter.
