My suggestion would be try for some remote access SAP IDES. IDES is the educational/student version.
Many 3rd party vendors offer remote system access to SAP servers hosted on their racks + BASIS services. Choose your product/module, like NetWeaver BI or R/3 for learning ABAP etc & purchase the evaluation version.
Evaluation SAP software is the exact form the one SAP AG uses in their training centers. Its better to have a first hand look & explore opportunities, as SAP is just vast!
All the best.
