Migrating SAP ECC system to S/4 HANA latest version-Impact on SAP EP perspective

[prasadv321]

Hi Experts,

Currently we are using SAP NetWeaver Portal 7.5 which is integrated with different systems (SAP ECC, BW, CRM...etc..).

As per the plan currently we are planning to migrate only the existing SAP ECC system to S/4 HANA latest version.

from the EP perspective, we have standard WebDynpro Java, custom WebDynpro ABAP and Transaction Iviews and UWL are accessed via SAP Portal 7.5 by the end users.

Please let me know we need to take care or will face any issues in all the applications (WDJ, WDA and Transaction Iviews) as it is in SAP Portal 7.5 after the migration of ECC system to S/4 HANA by establishing the SSO.

I have following questions related to this migration:

1) is it will impact on which areas in EP perspective?
2) What are the advantages and disadvantages from EP perspective?
3) Currently All standard WDJ applications are accessed via Destinations (Model and Meta Data Destinations) in the existing ECC system for the RFC calls. so after the migration of SAP ECC to S/4 HANA can we still establish the Model and Meta data destinations call to the S/4 HANA system from Portal 7.5 for the RFC calls.
4) Do we still need NetWeaver(NW- EP server) box when we move to S4HANA.

Request you to please help on any existing blogs and share your inputs on this.

Thanks you in advance.

Regards,
Prasad

Hi Prasad,

Are you using Fiori launchpad for the UX. There should be either EP or Fiori Launchpad where user will able to login and access the application.
