Cross-Device Analytics provides two distinct methods to stitch data together. This method relies on an Analytics variable, such as a prop or eVar, to contain a person identifier. It uses that variable as a base to link devices together.
If you intend to implement Cross-Device Analytics using field-based stitching, the following are required. Work with teams within your organization and your Adobe Account Manager to ensure that you meet all of the following.
Failure to meet all prerequisites can result in the inability to enable Cross-Device Analytics or poor results when stitching data.
Once your organization meets all requirements met and understands the limitations, you can start Setting up Cross-Device Analytics.
