Hi spride,
I took your advice and adjusted my workflow to include the mentioned modules - com.vmware.library.vcac.deleteEntity module.
It removed the entity from the vRA. I have verified this by going to Infrastructure -> Managed Machines. However, I still see a dormant entry under Items -> machines and I can't do any action on it. The detail tab shows "MachineID parameter missing".
Have I missed steps?
Thanks,
Jimmy
