Developing in ABAP in Standalone WAS - What tables & BAPI's are there?

[Former Member]

Hi,

We are planning a bsp web application project around stand alone WAS that is to communicate with R/3 4.6C mainly with RFC.

The question is: How is development on a standalone WAS different from development on mySAP ERP on WAS? In other words, When we install / purchase a standalone WAS license (6.30) - what will be included in the installation (license) - Do we have the same BAPI's, tables and Function modules available as in R/3?

Or do we have to copy or build these from scratch?

Thanks for your reply. Interesting information indeed.

In our case, we will probably need to build some tables locally in the WAS - I was just wondering if some standard table structures exist in the was installation (I suppose not...) that we could refer to while in coding.

Anyway, many thanks for your answer - it was interesting to hear your experioences of a similar project.

Hello Jorma,

I also installed a WAS 6.20 to do exactly the same thing you are going to do. I my case we developed a BSP to call someone's (a users) payslip from another R/3 (4.6B) system. It worked like a charm and the whole thing took about three days. We had never even worked with BSp's before.

If you call a bapi from an empty WAS server, the bapi you are calling is in the target system. It doesn't need to be in the source (WAS) system. As long as you have an RFC connection from your WAS to an R/3 system all the bapi's you see when you call transaction 'BAPI' in the target (r/3) system are also 'callable' from your empty WAS system. This also goes for the tables and functions. They are not in your WAS system, but you can call them with bapi's from your WAS system.

I hope this answers your question (and I hope the answer is correct because I'm not a developer, if not please correct me.)

Kind regards

PS. A 'standalone' WAS costs you nothing if you are already an R/3 customer. If not I'm guessing you have to pay for the WAS but I'm not sure.
