Stuart,
Thanks for the response.
All in all web dynpro ABAP is go forward for ESS - this is what I understand. I will see any delta services in release notes for EHP6. I am good there.
My major concern is regarding MSS and any other config. around that. Is MSS in WD4ABAP with EHP5 or still WD4JAVA.
Please let me know. Also HR255 course covers both ESS, MSS from application point of view. It does not describe the technicalities. So I am not getting good feeling about MSS and what all do I need to focus in relation to this one.
Please suggest.
Regards,
Bharat
