Hi,
We currently have embedded gateway solution on our 7.31 CRM ABAP system, we have also installed SAP UI add-ons 1.0 SP14 which has moved our UI5 version to 1.28.x. Gateway components version are as follows
GW_CORE - release 200 SP11
IW_BEP - release 200 SP11
IW_FND - release 250 SP11
IW_GIL - release 100 SP7
Our objective is to develop latest UI5 features like OVP (Fiori Overview Page), etc. for which we are required to have SAP UI add-ons 2.0 release. We have no requirement to use any SAP Fiori apps, we are custom developing SAP UI5 applications and publish it on the FLP.
For SAP UI add-ons 2.0 release the requirement is 7.4 or 7.5 ABAP stack and unfortunately we cannot install it on our 7.31 since it has dependency on SAP_BASIS core component and many other core components. We do not want to upgrade business system at this stage. Hence, we are looking at setting up HUB gateway solution to isolate the release and development of Gateway/UI5 from our business systems.
I have read some blogs on various options (SAP Gateway deployment options in a nutshell) and also recent sap sysarch Jan-2016 gateway session but I couldn't get clarification on below question
We would like to use Gateway deployment options-1 (based on above blog). If I stand up a new HUB gateway system on new 7.5 release with latest Gateway and UI5 versions, there is still dependency on IW_BEP component on business system.
Reading the sap note 1830198 - SAP NW Gateway: Dependencies Between IW_BEP and IW_FND I understand that
As of SAP NetWeaver Gateway 2.0 SP06, it is possible to have a higher version of SAP NetWeaver Gateway enabling component installed.
What I like to understand and get clarification is, if we leave the IW_BEP component on business system at lower release (i.e. 200 SP11 as per my first paragraph) and keep the new HUB system components at higher release all the time, can I still develop/deliver latest and greatest functionality of gateway functionality ?
Isn't there any dependency that I need to sync the version of IW_BEP component on 7.31 ABAP system to the HUB release of gateway ?
We don't want to be in a position after installing HUB systems that we also have to upgrade our business system to 7.4 or 7.5 just for gateway functionality.
Also, very soon SAP is going to release gateway based on ODATA 4.0 version, in this case we can upgrade the HUB system with latest release but what about IW_BEP components on business system?
Regards
Siva
