Four months ago I installed a Netweaver 2004s with XI system for demo and test purposes. Now reading about our next installation ECC 2005 I found out that I'll need to install Solution Manager for this version (because of the key).
I was reading about SolMan but still dont get how it is installed. I know that is a technical environment that provides diagnosis, support, installation keys, central monitoring and administration , etc. but I dont understand if it needs an additional installation before to start installing the ABAP or/and JAVA instances of a SAP system. Does the SolMan installation is included in the SAP installation? or do I need to "change" the first installation DVDs if I want to make a SAP installation with SolMan?
Can I install SolMan in an existent system? I would like to install it in the Netweaver system we have, but reading the docs I guess you need to install the SAP system from zero and install first the Solman.
