Hi Christophe,
thats a good idea.
I attached 3 screenshots.
the picture "vco_WF_Delete_Snaps_for_Single_VM_Params.PNG" views the Workflows Output Parameter.
This WF should be called in the foreach element.
The pictures "vco_WF_Delete_Snaps_for_VMs_IN-Param.PNG" and "vco_WF_Delete_Snaps_for_VMs_OUT-Param.PNG" shows the INPUT/OUTPUT bindings of the foreach element to call the WF for single VMs.
May be i am at the time a blockhead...
best regards,
Mike
