Since SAP ECC 5.0 and ECC 6.0, SAP has integrates its SAP Internet Transaction Server (ITS) on its server. You don‚¬„¢t need to install separate ITS server. You just need to activate and configure it.

When you have (or planning to have) more than one SAP instance on the same server, it may happen that you will need to run SAPinst at the same time as somebody else.
