I added a new evar( customer id) to the Report Suite in production but the rule that will hit this evar is not active yet. I noticed that this evar has undefined value for each beacon has been sent to the Report Suite. How can I avoid to populate this new evar with undefined value until i dont bring in production the rule will hit this evar?
"I understand the reason of undefined value, what is your advise when we add a new evar in DEV Report Suite and PROD Report Suite but the rule will hit the evar in the PROD Report Suite will bring in PROD later?"
The recommendation is to continue testing and sending data to only the DEV report suite. After the changes are verified, the rule should be published to production with the evar hitting and sending data to PROD report suite. It will minimize the "Unspecified" instances.
