Here are some frequently asked questions around stitching:

Move across channels

How can I use stitching to see how people move from one channel to another?

You can use a Flow visualization with the Dataset ID dimension.

  1. Log in to Customer Journey Analytics and create a blank Workspace project.
  2. Select the Visualizations tab on the left, and drag a Flow visualization to the canvas on the right.
  3. Select the Components tab on the left, and drag the dimension Dataset ID to the center location labeled Dimension or Item.
  4. This flow report is interactive. To expand the flows to subsequent or previous pages, select any of the values. Use the right-click menu to expand or collapse columns. Different dimensions can also be used within the same flow report.

If you would like to rename dataset ID dimension items, you can use a lookup dataset.

Replay

How far back does stitching replay visitors?
The lookback window for rekeying depends on your desired frequency of data replay. For example, if you set up stitching to replay data once every week, the lookback window for rekeying is seven days. If you set up stitching to replay data every day, the lookback window for rekeying is one day.

Shared devices

How are shared devices handled?

In some situations, it is possible that multiple people log in from the same device. Examples include a shared device at home, shared PCs in a library, or a kiosk in a retail outlet.

The transient ID overrides the persistent ID, so shared devices are considered separate people (even if they originate from the same device).

See the Shared devices use case for more details.

Many persistent IDs

How does stitching handle situations where a single person has many persistent IDs?

In some situations, an individual user can associate with many persistent IDs. An example is an individual frequently clearing browser’s cookies or using the browser’s private/incognito mode.

For field-based stitching, the number of persistent IDs is irrelevant in favor of the transient ID. A single user can belong to any number of devices without impacting Customer Journey Analytics’s ability to stitch across devices.

For graph-based stitching, a single person can have many persistent ID in the identity graph. Graph-based stitching uses the persistent ID based on the specified namespace. In case there are more persistent ID for the same namespace, the lexicographic first persistent ID is used.

Stitching process

Once I contact my Adobe Account Team with the desired information, how long does it take for the rekeyed dataset to become available?
Live stitching is available approximately one week after Adobe enables stitching. Backfill availability depends on the amount of existing data. Small datasets (less than 1 million events per day) typically take a couple days, while large data sets (1 billion events per day) can take a week or more.
