I had a query that was pulling in Event Type, Event Time, Object Name and a few other things.
I noticed that for reports where I right click and select View that I was getting two View rows within seconds of each other so was trying to determine what they were.
I decided to pull in Client Application Type object to see if it might assist with my analysis and when I did this the majority of the rows were no longer returned.
So then I went to the universe in IDT to see where that object was coming from.
I saw it was located on table ADS_CLIENT_TYPE_STR via a join from ADS_EVENT.
Immediately I knew that if rows were being excluded it was because a value in ADS_EVENT did not have a corresponding value in ADS_CLIENT_TYPE_STR - basic SQL knowledge.
So then I added Client_Type_ID from ADS_EVENT as an object to the universe and pulled that into my original query and found the most common entry was AbI5_LpMFxFLhxl7DV91KYY and this was the one that disappeared when I also included Client Application Type.
So I went back to IDT and used the show values option to see what the entries on the ADS_CLIENT_TYPE_STR table were and it has 49 entries but AbI5_LpMFxFLhxl7DV91KYY is not one of them.
Hopefully that clarifies things.
