I’ve generated live proof(E2E) for Losses and Gains campaign again. I found the same error last time.
However, I’ve checked the query to return (1) as you suggested.
select count(1) from ua_treatment, VW_CAMPAIGN_ATTRIBUTES where ua_treatment.campaignid = VW_CAMPAIGN_ATTRIBUTES.campaignid
and treatmentcode in ('000052260') and CAMPAIGNOUTPUTFILE = 'Cover to Cover Comparison';
Could you please be advise?
