PI POST INSTALLATION STEPS

After a PI installation you have to configure your system. 
This is a mandatory post installation step called "Running the Configuration Wizard".
Before running the Wizard, it is recommended to update the following Java Software Components (SCs) to the highest available Support Package and Patch Level:
Life Cycle Management:

LM CONFIGURATION (LMCFG)
LM CONFIGURATION WIZARD (LMCTC)

Process Integration:
    MESSAGING SYSTEM SERVICE (MESSAGING)
    XI ADAPTER FRAMEWORK (SAPXIAF)
    XI TOOLS (SAPXITOOL)
    PI GUI (SAPXIGUI, only 7.11)
    PI GUILIB (SAPXIGUILIB, since 7.30)
    ESR (SAPXIESR)

The ABAP stack must have the same Support Package level as Java.
This Wizard Template is available since Release 7.10.

A prerequisite to run the Wizard is that the system was installed with the PI Installer (SAPInst). All PI services must be up and running.
