ESS services using WDA

Question

Do we have any standard framework like FPM to develop ESS applications using WDA?

Answer 1

Hi Pankaj,
as you have seen, ESS calls a bunch for functions many called
XSS* or HRXSS*
When implementing custom Web Dynpros, to replace or augment
standard Java WD apps, you can call the same functions that the JAVA WD call.
Use st05 to set up an RFC trace.
You can watch which functions are called on the various ESS transactions.
I recommend WDA for custom ESS forms to customers who have limited JAVA, no DTR  in use,or who are concerned about the upgrade support for their JAVA code changes.
It is often easier and youget less upgrade issues, when you build a custom interface in WDA before making large changes to standard SAP java source.
Small tweaks in JAVA may be an exception.
Please open another thread for the debate When to use JAVA WD and when to use WDA.
I want only to point out, you can use JAVA and WDA side by side.
Build custom WDA apps and call the same functions use by standard ESS.
The RFC trace tool is a great place to start.

Phil.
