"System Internal Context" timeline updates don't show in the Buzz Activities - why?

[Berto2002]

I have just put a report together to report on the chronology of updates on the timeline of requests. The h_buz_activities (com.hornbill.servicemanager) table holds the data

In the report, I have a mismatch in the count of updates on the timeline of the Request and the rows of the Buzz Activities. The discrepancy is that the System Internal Context timeline entries are not showing in the report.

 

Is this expected and why would they be missing from Buzz Activities?

I note that the initial logging DOES show as a System update:

@Berto2002 what is the report filter? What criteria are you using there?

[Berto2002]

At present only this. The target ID value is only to display all the results for one of the Requests since I understand target ID is a cross-reference to Request

@Berto2002 there is no inherent exclusion of the System Internal Context updates. These entries, for some reason, are not matching the criteria in the filter, i.e. the published date for these is not > StartOfYear or they don't have that Target ID (might be that these entries do not have a published date value, possibly...)
