Is there documentation for the proper way to amend a lease, to renew/extend the terms, for example?

We implemented Asset Management with FASB accounting standards in July. The instructions for creating a lease after conversion were very helpful. We now have a need to amend some of our leases for various situations, such as correcting the department, renewing/extending the lease terms, or transferring to another business unit, and are looking for similar instructions to guide our SMEs.

PeopleBooks tells on which pages these activities can be performed, but is there any guidance on the best method and sequence of steps to accomplish these tasks? In attempting to correct a deptID, we had significant trouble because some patches needed to be applied.
