Workflow Custom Activity / Set

Hi,

I followed the guidelines from "Create a Logging Custom Activity and Deploy it to the FIM Portal"

 https://msdn.microsoft.com/en-us/library/ff859524.aspx?f=255&MSPPError=-2147217396

and it worked fine with a workflow MPR. I can see the type of the operation performed and the resource attributes that changed.

Now, when I use it on a Set MPR I don´t have the same information. Should I use a workflow MPR for that? I mean to know if a resource in that set had an attribute value change?

Many, many thanks,

DD
