Hope you have gone through that blog.
Permits are approvals which will be created as one time master data & the same can be used for many orders.
So, it doesn't have any number range. Also, this master data is very limited.
You can't set the validity date range for permit, I feel.
Instead, in IPMD, you can sen Usage Block that will avoid the usage of that specific permit further.
Suggest you to read some documents & links on permits to understand the concept.
You can get the links in google.
