Can referrer value be overwrittten?

[#1]

Hi!

Since we are having a lot of problems with the referrer report dealing with blank values, we want to override the referrer value in our GTM: whenever there is no referrer, we write a String value.

However it doesn't show up in referrer report. Is referrer report only accepting blank or URLs?

Yes, spaces and other non-URL characters will be removed if they are set in the variable.

Had an issue where I noticed this.

Unfortunately we don't, we create the imag tags by ourselves and send them to adobe. We tried to overwrite the "r=" parameter with a string (not an URL), but it won't populate the reports. So my assumption is that the value must have the structure an URL?

If you're using an s_code implementation, s.referrer would be the variable you'd want to overwrite to ensure it is populated.
