SAP ADS System Landscape
For one of our customers, we have installed SAP ERP 6.0 with a landscape of 3 systems (DEV, QAS, PRD). We have to connect ADS ( ASJAVA) to ERP DEV, QAS and PRD, in this scenario should we have a landscape of 3 systems (DEV, QAS, PRD) also for sap as java ads usage type, or we can just use one as java system and connect it to SAP ERP DEV QAS PRD.
What are the SAP prerequises (license) for using ADS with ERP in landscape of 3 systems ?
Thanks in advance ?
