I am working on the feasibility of installing PO 7.4 in our project.
Our Current landscape includes the following systems that need to be connected to PO 7.4
Please let us know if any upgrade is needed in the connected systems as a prerequisite of PO 7.4 installation.
From the SAP Upgrade Dependency Analyzer I cannot see any need for upgrading the version or service packs in ECC or CRM.
Please provide your inputs on this.
