There are a lot of functionality that are in the "grey area". For example, SAP BI runs perfectly fine as AS-ABAP only but there are some functionality that require AS-JAVA. Your best bet is to find out what application / functionality you require from SAP, then research to see if what you are after requires AS-ABAP and/or AS-JAVA.
