Ø  About SAP NetWeaver Gateway

SAP NetWeaver Gateway is a product from SAP that provides access to SAP Business Suite data for lightweight, people-centric applications that can run on a variety of devices and application platforms.

SAP NetWeaver Gateway act as a bridge between the traditional environment of the SAP Business Suite and lightweight needed applications.

SAP NetWeaver Gateway supports the Open Data Protocol (OData) which is a web protocol for querying and updating the data.

SAP NetWeaver Gateway can be deployed in one of two ways in an SAP landscape:

• Standalone in which SAP NetWeaver Gateway is deployed on a dedicated server. We call it as External Gateway.

• Embedded. Gateway is installed as an ABAP Add-on and runs on the same system as the SAP Business Suite, so no dedicated server is required to run Gateway. Meaning business logic and data exists in the same system.

       

For Remote Gateway, RFC connections are used to fetch data from a system.

For e.g. Suppose you have a HCM system, CRM system etc separately installed in a Customer landscape.

For cost efficient measures, Customer can have a single gateway system from where they can get data from any system either HCM, CRM etc.

So it’s like the hub, like your internet connection. You have a single modem serving many computers, where all systems interact to outside webpages via the gateway

In this scenario, Gateway servers as a security measure so that the actual system is not exposed to outside world.

Gateway Configuration is done so that you test the application in both local and remote gateway (covering all scenarios like HANA and normal db tests). We also have external and local gateways tests so that application should work seamlessly across any setup.

                Some more info:

Q: Is gateway valid for UI5 topics only or is it valid for lower releases also??

A: For any UI5 development gateway is valid. We have to perform these tests ideally. Now this is again up to the product team do the gateway configuration. It’s up to the team which is developing the application; their PO or DM has to give the directives.

Ø  Checking OData Services in Corresponding Gateway

Local Gateway:

You can go and check the services detail and OData activation in transaction “/iwfnd/maint_service” in given backend system .

Here, you will get technical name and description of the services, along with that you will see OData activation detail. Also, since it is local gateway so SAP system alias will be maintained as local.

2.            External Gateway:

You can go and check the services detail and OData activation in transaction “/iwfnd/maint_service” in given Gateway system .

Here, you will get technical name and description of the services, along with that you will see OData activation detail. Since it is an external Gateway, SAP system alias should be maintained with backend system.

Note: If one Gateway system is connected to more than one Backend system. Then we required an additional role like “Y_CLIENT_<System>_<Client>” assigned to your user, related to that particular Backend system and Client detail.

Ø  Configuration of SPB

The Suite Page Builder (SPB) is a UI development toolkit for HTML5 (SAPUI5) applications that acts as a framework to run Collaborative Human Interface Parts (CHIPs). A CHIP is an SAPUI5 application that adheres to specific binding contracts that the SPB defines.

The Suite Page Builder can be configured using the SPB Administrator Page that provides the CHIP and catalog configuration features. The administrator has access to the Administration Page and all of the catalogs in the system. Administrators can perform the following actions:

1.     Add CHIPs to the catalogs

2.     Delete CHIPs from the catalogs

3.     Decide which catalogs are displayed in the end user’s Suite Page Builder

Ø  Maintaining SAP Gateway OData Services

1.     Maintain System Alias

1.1 Create a RFC connection with Type 3 in transaction SM59.

1.2 Local Gateway: Create a local system alias in the Q system.

1.3 External Gateway: Create a system alias in gateway system pointing to Q system.

SPRO Path:

         

          

2.     Add Suite Page Builder Catalogs

Transaction -> /iwfnd/maint_services

Or,

Navigation Path: SPRO -> SAP Netweaver Gateway-> OData Channel -> Administration -> General Settings -> Activate and Maintain Services

Activate the following OData services for the Suite Page Builder Catalog:

·          /UI2/PAGE_BUILDER_CONF

·          /UI2/PAGE_BUILDER_CUST

·          /UI2/PAGE_BUILDER_PERS

                3.     To Activate Services in a System.

3.1 Click on “Add Service” button.

3.2 Add the system alias created in step (2) according to the gateway used and hit “Enter”.

3.3 Click on the service to be added.

3.4 Ensure that ICF Node is maintained as “Standard Mode”.

3.5 Save the service in local package.

3.6 Click on “Continue” button till success pop-up comes.

3.7 Go back to the previous screen and check the service that is recently added.

3.8 Double click on the Service and check that

3.9 ODATA is active in “ICF Node” section

·          To activate ODATA, use the navigation menu provided in “ICF Node” button.

·          The system alias should be according to the external/local gateway used

·          In case one service is called in many backend systems, then define a specific system alias (e.g., for a user role) by adding new system alias using   “Add System Alias” button.

   

              Similarly, add other SPB catalog.

  4.     Activating ICF Nodes for Services

Go to ABAP backend system and activate services in transaction SICF

·          Default_host -> SAP -> bc -> bsp -> sap

o    ARSRVC_SUITE_PB

o    ARSRVC_SPB_ADMIN

o    ARSRVC_LPD_C

·          Default_host -> SAP -> bc -> ui5_ui5 -> sap

o    ARSRVC_SUITE_PB

o    ARSRVC_SPB_ADMIN

o    ARSRVC_LPD_C

·          Default_host -> SAP -> public -> bc

o    ui2

o    ui5_ui5

In addition to above services, activate following SICF services as well in transaction SICF

·          Startup Service: /default_host/sap/bc/ui2/start_up

·          Image Upload Service:/default_host/sap/bc/ui2suite/image

Ø  External SAP NW Gateway System has a Different Client to the Backend ABAP System

To avoid an incorrect client user credentials request when running Suite Page Builder, configure the ICF nodes as described below:

1.   In your ABAP backend system, go to transaction SICF.

2.     The Maintain Services screen displays.

3.     Choose Goto -> External Alias.

4.     Select “Default Host” and choose External Alias -> Create.

5.     Choose “Trg Element” and navigate to SAP -> BC -> UI5_UI5 -> SAP.

6.     Double-click the SAP node.

7.     In the “External Alias” field, enter /sap/bc/ui5_ui5/sap and enter a meaningful description.

8.     Choose the Logon Data tab. In the Procedure field, select Required with Logon Data.

9.     Enter the backend client information as required and save your entries.

10.   Log on to SAP NetWeaver Gateway system, call transaction SICF and navigate to the respective service that the landing page uses.

11.   Double-click the service PAGE_BUILDER_PERS.

12.   Choose the Logon Data tab. In the Procedure field, select Required with Logon Data.

13.   Repeat the steps (10- 11) also for the following services:

·         PAGE_BUILDER_CONF

·         PAGE_BUILDER_CUST

Ø  Testing the Admin Page

After all of the prerequisite configurations are done, you must now be able to run the SPB admin page.

The SPB Administrator page can be launched with the URL.

https://<server>:<port>/sap/bc/ui5_ui5/sap/arsrvc_spb_admn/main.html

Ø  Setting up HR Professional

Using SAPUI5 technology, the landing page is a web-based UI for HR professionals offering a single point of access to employee and organizational master data.

Activate the required services for your application in the corresponding system and check the respective application in the landing page.
