I created a BizTalk demo project with BAM Activities on a new build environment and ran some tests. BAM Activities data were populated in _CompletedView and _RTAView views.
However, the BAM Portal’s Aggregations pivot table view failed to load with the error below:
Failed to get data. If available, errors returned from the provider are listed below.
* An error was encountered in the transport layer.
* The peer prematurely closed the connection.
Disable the “Enable Protected Mode” option in Internet Explorer under Tool / Internet Option / Security (tab)
