Hi,
when using runbook activity "Update Activity" to update activity status I run into the the following error:
[9ac3fcb2-a046-140d-f38c-8c4bf9528680] is not an instance of class [Microsoft.SystemCenter.Orchestrator.RunbookAutomationActivity].
If I proof this GUID via PS-API, the result is the correct object:
>Get-SCSMClassInstance -ID 9ac3fcb2-a046-140d-f38c-8c4bf9528680
.
.
.
#FullName : Microsoft.SystemCenter.Orchestrator.RunbookAutomationActivity:RB593
.
.
.
Following screenshot shows the settings the Runbook-Activity "Update-Activity".

The workaround is to update status via Runbook-Activity ".NET-Script", but I still not know why I run into an error if I use the Runbook-Activity "Update-Activity".
Similar issue described here.
