EPM Budget Revisions - Functionality difference between Permanent, Temporary , Transfer

with EPM Financials Module - Budget Revision functionality, Is there any functionality difference between the Revision types of Permanent, Temporary and Transfers.

From our observation all three types update the Adopted Budget/Working version in EPM when the "Approved and Funds Reserve" menu is selected . This process also updates the Adjusted Budget column in the Control Budget in ERP. The expectation is that the Permanent revisions will be included in the base budget or Revised Budget, while temporary revisions will not. Also the expectation is that transfers should net out to zero and ideally there needs to be Temporary and Permanent Trnasfers as well.
