Can we program in JAVA in mySAP to build an application equivalant to ABAP?

If yes, then how much JAVA is essential? is basics fine? or advance concepts are required?

Theoretically its is definitely possible, but you might face a lot of practical difficulties. For one, all your application tables are in ABAP and for each operation you would have to call the ABAP table. As far as I know, the dictionary-level integration between ABAP and Java is not fully functional yet.

Secondly, each time you would have to do a Jco call to the ABAP engine to pass back values/call an FM in the system, etc. That would add to the time taken by your app.

You would require a very good knowledge of java to be able to code an entire app.

Hi,

ABAP is tightly linked with database/tables operations.

You won't have this using Java because JCo relies either on RFCs or on IDocs.

Thus, anyway, you would have to code the low-level in some RFCs of your own...

Best regards,
