I suggest starting here for configuration steps and instructions:
Overview and Prerequisites - Configuring Process Integration After Installation - SAP Library
If you just want to run a single stack Process Orchestration system then it's my understanding that I needed to run the "Process Integration and Orchestration Package" (PI-CP) wizard. After consulting a friend who had done a PO 7.4 installation last year, I decided to run the "System Landscape Directory" wizard first just to make sure the SLD was already properly configured and CR CONTENT was up-to-date before proceeding with the other functional units.
You should be able to disable your previous configuration and proceed with the "Process Integration and Orchestration Package" functional unit.
