I have uploaded data(.csv) in people and authenticated the customer id(present in same csv) in Adobe Launch. After doing so, i have checked in network call, across id:<customerid> is coming. So, how can i validate the same in reports or how can i check the same data in Adobe Analytics.
If you have sent the custom ID in the analytics server and also uploaded the data by creating the data source in customer attributes. You would see the customer attribute uploaded attributes as reports in Adobe Analytics under Visitor Profile Menu Item.
Report & Analytics -> Visitor Profile -> Customer Attributes
