As of now our SAP PI 7.11 version is communicating with few systems through MQ channel<<such as Manhattan warehouse system,Logics and few others>> and some R3 systems are directly interearcting with MQ system through some function module call and finally data is going to some other system and Mainframe is also interacting with MQ for pushing and pulling data that is received from outer world OR for passing data to WDI[EDI system]/SAP R3 OR few legacy system.
in crux MQ is getting used in our landscape as data carrrier for Queue based processing.
Can this MQ application be fully replaced by SAP PI and SAP R3 ALE/IDocs technology.
Please guide me as to how this can be achieved
