Hi,
A lot of people have noticed in 6.x that Change Lease is less than ideal. This may change in 7.x (no idea), but for those who have ASD in 6.2.x and are struggling with lease constraints, I have attached a workflow that will allow you to create a Resource Action that sets Goal Posts for your change lease requests. (e.g from now to one year from now, otherwise request not allowed) Hopefully a few people will find it useful.
You will have to either:
1. Create a configuration element for cafeHost and lease-months attributes.... and then bind them to the workflow.
-or-
2. Just set them in the workflow to what you want (attribute values).
This could also be run, supplying a VC:VM and a Date value, from within another workflow, but I put it together based on it being a Resource Action Request. When you create your form in ASD, I recommend you add a field and set it to a Default Read Only VM.name value. Like below...
Let me know if you have any questions.
Cheers,
Sean
