Embedded hub model

[Former Member]

Hi Team,

We are going for the Embedded hub model and we have 2 multiple back-ends servers (ECC and SRM)

We are using ECC system as an Embedded system for Front end and Back end components.

As per approach we will load all the SRM(PO) related frontend components/ECC(HCM)frontend components( UISRM200 100, UIHR001 100) as well as all Central and gateway add-ons in ECC system.

We will also load all backend add-ons in ECC (GBX01HR 600 - SP 0) and SRM.

In this scenario how many launch pads comes up, as we are using ECC system for Launchpad and also we are using SRM backed to get PO data.

We are going for 3App (SRM,ECC) and our daily volume for these 3 application transactions are not more than 1000.

Will it be suitable for Production environment as client is not willing to go for Central Hub.

Please provide your suggestion for the above points.

Regards,

Krishna

Hi Krishna,

There are other options for landscape setup. How about using SAP Fiori cloud edition? See the diagram No.1 Cloud+ERP.

Hi Krishna,

Regarding your question, below you can find the answers:

1) how many launch pads comes up?

You are going to have just one launchpad that will be located in your ECC server.

2) Will it be suitable for Production environment?

It will not be suitable for production to use a SAP Business Suite System with embedded deployment as a hub system for additional backend system.

The reason is that this might lead to a situation where the SAP NetWeaver Gateway release of the hub system is lower than the version of the SAP NetWeaver Gateway backend components of the remote backend system.

Such a situation can occur because it might not be possible to upgrade the hub system at the same time as the backend system. Internal policies might dictate that a SAP Business Suite system that is used as a hub must not be upgraded.

To avoid such a situation the recommended approach is to choose one of the following options:

1. Use embedded deployment option for your SAP Business Suite systems
2. If you go for a hub based architecture you should use a dedicated SAP NetWeaver Gateway Hub system that should run on the latest release of SAP NetWeaver Gateway.

Thanks Emanuel.

I understand the inconsistency between the NetWeaver Gateway release of the hub systems.

Ex systems configuration as below.

ERP- Gateway release as

• SAP_BASIS_740_0008
• SAP_ABA_740_0008
• SAP_GWFND_740_0008
• SAP_UI_740_0008

SRM- Backend release as same:

• SAP_BASIS_740_0008
• SAP_ABA_740_0008
• SAP_GWFND_740_0008
• SAP_UI_740_0008

While upgrading if we consider SAP ERP gateway add-on’s, SRM gateway ADD-ONS or same level or higher level then it won’t be a problem right?

Apart from that is there any impact on this transaction load? As our current production load for those 3app(Srm+ecc) are not more than 1000 in a day.

And also BI/PI systems are integrated to ECC system, will it be considered in those system Gateway add-on’s as well?  As we are not using for those systems app’s. (BI/PI) .

As I mentioned, this is not a good long term solution because of the different upgrade paths systems may have.

The gateway add on has to be installed just in the system that will be used as a gateway.

In case you want to use several systems with an emmbedded deployment type, the gateway add-on should be in each of the systems.

If the answer was helpful to you, please consider the thread as answered.

Emanuel

Thanks Emanuel.

As we have a different upgrade paths (Integrated ECC->BI/PI/SRM), we are planning to Fiori app’s for only ECC(HCM) and SRM (P.O). As we are maintaining same levels of Gateway NetWeaver 7.4 for both ECC and SRM systems.

However, we are not maintaining Gateway add-ons to other BI/PI systems.

In future if we want to upgrade for ECC and SRM and consider the same level of Gateway add-ons then it will not be any issue I believe. Please suggest your opinion on this.

Krishna.
