I've handling some legacy applications running on WMB and am trying to work out how to find which main flows a particular subflow belongs to. Seems an obvious thing to be able to do but I can't seem to find it???? Grrrr
I'm using Broker Application Development 6.0.2
The toolkit does support the feature in v7 I think - you can use the Impact Analysis to identify this.
I think there's a search string you can use... I used to have it saved somewhere. You basically want to search inside all of the .msgflow files as text / xml and find references to the name of your subflow file.
