I'm trying to run Readiness Check for "Upgrade" on S/4 1909 system. I've followed the SAP note "3059197 - SAP Readiness Check for SAP S/4HANA upgrades" and implemented all required notes.
Now when executing the program RC_COLLECT_ANALYSIS_DATA, the following erro occurs and I cannot Schedule Analysis: "The system is already a SAP S/4HANA system. This is not supported.The system is not a SAP ERP system. This is not supported.".
How can I run the RC for Upgrade in a system alredy in S/4 ? Thank you.
