Hi I have a questions about uploading post sales data into GA. We are a lead generation company gathering data which is sold onto Financial Advisers, most of our traffic/leads come from PPC. A number of the leads we generate are rejected by the financial advisors due to various reasons (wrong telephone numbers, fictitious details etc). Within our back end system we can track whether a lead has been Rejected or Accepted (down to keyword level) using query parameters in the destination URLs. Each lead has a 'Lead ID' attributed to it (whether it is rejected or active), the lead ID is the same as the Ecommerce Transaction ID in GA. We are using Universal Analytics. Is it possible to import data from our back end system in order to match up the rejection/active lead data with the marketing activity at Channel/Campaign/Adgroup/Keyword level? I hope this questions made sense. Cheers Mark
