We have a SAP ECC 6.0 system double stack (EHP4 FOR SAP ERP 6.0 / NW7.01).
We would like to install SAP PI 7.1 in order to implement several adapter scenarios (RFC, IDOC, Proxy, etc.)
What are the prerequisities for the installation and which options can be choosed here?
a) new NetWeaver installation with SAP PI 7.1
b) nstallation on top of SAP ECC 6.0 system
c) other scenarios
Any helpful information will be very appreciated
