Just installed fresh ERP/ECC 6 from disks labeled EHP4 ready. Needing to upgrade immediately to EHP4. To do this, my understanding is that I need to initiate a maintenance transaction from solution manager to start the process and then proceed (basically following these directions http://sap.wsteinert.com/blog/2009/10/implementing-the-ehp-4-part-2/ ).
Can anyone describe (in detail) the maintenance transaction process and what I have to configure on the solution manager side to get this up & going?
Also, does the EHP4 process require that I download the components? It looks like I already have some media that may have EHP4 components on it. Can I just do a local upgrade using the media?
