I am encountering difficulties when I start selecting a big number of deliveries and then press a specific report.
By specific report I reffer to "URL's and click streams" and/or "Breakdown of opens".
Big number, from what I experienced, is bigger than 145.
When I click on the report button after selection nothing happens.
The question is the following: "is there a standard maximum number of deliveries that need to be selected for the reports to work?" (assuming that after the selection is made the report icons are still there and clickable)
Yes I confirm such a limitation, existing for many years (I knew it in 2011/v4.0).
To my mind when I did a bit of analysis, it was due to the parameter size length exceeding the supported max value.
Anyway, IMO it is a best practice to split the deliveries in several folders for accurate analysis and/or manipulation/management, and select a few lines.
