Campaign variable evar0

[um_d]

why do we have specific variable for campaign in Adobe Analytics? Why cant we use evar or prop to capture the campaign value?

You can capture Campaign IDs in any of the evars/props. You just need to set pup your code to set the variable.

@um_d Evars and props are limited in numbers (255 and 75 respectively) and there aren't any provisions to have extra evars or props. As campaign tracking is the most common use case, we have provided that separately as that will help in saving one of your evars or props. However, you can always use another evar or prop to populate your campaign data.
