Hi Experts,

Here I am seeking some assistance and information for my better understanding on the risk factors for EHP7 upgarde - as of now client is at EHP3.

Since ESS/MSS is webdynpro Java based and now when we are looking forward for EHP7 technical upgrade not functional, we have got concerns on the custom application on ESS and MSS.

Please giude me with the impact on customised ESS /MSS application after EHP 7 upgrade.

We are finding it difficult to understand.

I would like to know much more info on EHP upgrade risk factors.

Looking out for revert.

Many thanks.

    As per my understanding - you can continue to use the custom java WD applications by customizing the newly delivered ESS/MSS roles.

    This could be done by modifying the launch for ESS and MSS if you opt NWBC or my modifying the ESS/MSS portal roles for the new release.

    Await inputs from others as well.

    Adding to my last update/concern, I would like to have more info on my below query please

    We are currently at below BP:

    SAP ESS 603 SAP MSS 600 and PCUI_GP 603

    and are planning to upgrade SAP Netweaver 7.01 to 7.4 and ECC 6.0 EHP 3 to EHP 7.

    1) We have done some customization on standard SAP ESS MSS java applications.

    As per your suggestion when we add new BPs to the SAP netweaver 7.4 then how our old webdynpro java customization on standard ESS / MSS applications will work with New BP - Kindly advice .

    2) How can we take our previous versions of ESS 603 MSS 600 code to SAP NetWeaver 7.4.

    There is a possibility of re-compiling the standard code but how much this is feasible.

    How can we take over custom on standard codes to the upgraded SAP Netweaver 7.4.

    Correct me please if I am not getting the stuffs properly.

    Your Expert input on this would be highly appreciated.

    Many thanks.

    Thanks for your valuable input.

    Could you please suggest if we can go with Webdynpro ABAP instead carrying Java.

    Is it recommendable to buisness to go with ABAP - since we are in due deligence phase, need to understand the consequences.

    We are at EHP3 having WD Java and ABAP both and while doing technical upgrade to reach EHP7, What could be the risk facorts if we leave Java behind and move with ABAP.

    Many thanks for your expert input.

    Thanks Siddarth,Yugandhar,Wilman and Sahir for your invaluable inputs.

    I am not closing this thread because we are still in due deligence phase , we may come across with some more doubts in very near future and hence can use this thread to get in touch with experts.

    At this point of time, our vision is clear at certain extent.

    Many thanks for all your support.
